Hadrian: trace the execution of expensive Cabal calls
We use Cabal to parse, configure, register and copy packages, which are
expensive operations that are currently not visible to Shake's profiling
infrastructure. By using `traced` we tell Shake to add these IO actions
to the profiling report, helping us to identify performance bottlenecks.
We use short tracing keys, as recommended in Shake docs: the name of the
current target is already available in the rest of the profiling
information.

Hadrian: introduce an easy way for users to build with -split-sections
Any user can now trivially build any number of Haskell packages with
`-split-sections` by using `splitSections`/`splitSectionsIf` on any
existing or new flavour:
-- build all packages but the ghc library with -split-sections
splitSections :: Flavour -> Flavour
-- build all packages that satisfy the given predicate
-- with --split-sections
splitSectionsIf :: (Package -> Bool) -> Flavour -> Flavour
See the new section in `doc/user-settings.md`.

Minor refactoring in copy array primops:
- `emitCopySmallArray` now checks size before generating code and
doesn't generate any code when size is 0. `emitCopyArray` already does
this so this makes small/large array cases the same in argument
checking.
- In both `emitCopySmallArray` and `emitCopyArray` read the `dflags`
after checking the argument.

Visibility: handle multiple units with the same name
Fixes #16228. The included test case is adapted from the reproduction in
the issue, and fails without this patch.
------
We compute an initial visilibity mapping for units based on what is
present in the package databases. To seed this, we compute a set of all
the package configs to add visibilities for.
However, this set was keyed off the unit's *package name*. This is
correct, since we compare packages across databases by version. However,
we would only ever consider a single, most-preferable unit from the
database in which it was found.
The effect of this was that only one of the libraries in a Cabal package
would be added to this initial set. This would cause attempts to use
modules from the omitted libraries to fail, claiming that the package
was hidden (even though `ghc-pkg` would correctly show it as visible).
A solution is to do the selection of the most preferable packages
separately, and then be sure to consider exposing all units in the
same package in the same package db. We can do this by picking a
most-preferable unit for each package name, and then considering
exposing all units that are equi-preferable with that unit.
------
Why wasn't this bug apparent to all people trying to use sub-libraries
in Cabal? The answer is that Cabal explicitly passes `-package` and
`-package-id` flags for all the packages it wants to use, rather than
relying on the state of the package database. So this bug only really
affects people who are trying to use package databases produced by Cabal
outside of Cabal itself.
One particular example of this is the way that the
Nixpkgs Haskell infrastructure provides wrapped GHCs: typically these
are equipped with a package database containing all the needed
package dependencies, and the user is not expected to pass
`-package` flags explicitly.

Improve performance of newSmallArray#
This:
- Hoists part of the condition outside of the initialization loop in
`stg_newSmallArrayzh`.
- Annotates one of the unlikely branches as unlikely, also in
`stg_newSmallArrayzh`.
- Adds a couple of annotations to `allocateMightFail` indicating which
branches are likely to be taken.
Together this gives about 5% improvement.

Fix faulty substitutions in StgCse (#11532).
`substBndr` should rename bindings which shadow existing ids.
However while it was renaming the bindings it was not adding proper substitutions
for renamed bindings.
Instead of adding a substitution of the form `old -> new` for renamed
bindings it mistakenly added `old -> old` if no replacement had taken
place while adding none if `old` had been renamed.
As a byproduct this should improve performance, as we no longer add
useless substitutions for unshadowed bindings.

Inline the definition of 'ap' in the Monad laws
The law as it is currently written is meaningless, because nowhere have
we defined the implementation of 'ap'. The reader of the Control.Monad
documentation is provided with only a type signature,
> ap :: Monad m => m (a -> b) -> m a -> m b
an informal description,
> In many situations, the liftM operations can be replaced by uses of
> ap, which promotes function application.
and a relationship between 'ap' and the 'liftM' functions
> return f `ap` x1 `ap` ... `ap` xn
> is equivalent to
> liftMn f x1 x2 ... xn
Without knowing how 'ap' is defined, a law involving 'ap' cannot
provide any guidance for how to write a lawful Monad instance, nor can
we conclude anything from the law.
I suspect that a reader equipped with the understanding that 'ap' was
defined prior to the invention of the Applicative class could deduce
that 'ap' must be defined in terms of (>>=), but nowhere as far as I can
tell have we written this down explicitly for readers without the
benefit of historical context.
If the law is meant to express a relationship among (<*>), (>>=), and
'return', it seems that it is better off making this statement directly,
sidestepping 'ap' altogether.

configure: Always use AC_LINK_ELSEIF when testing against assembler
This fixes #16440, where the build system incorrectly concluded that the
`.subsections_via_symbols` assembler directive was supported on a Linux
system. This was caused by the fact that gcc was invoked with `-flto`;
when so-configured gcc does not call the assembler but rather simply
serialises its AST for compilation during the final link.
This is described in Note [autoconf assembler checks and -flto].

Fix Uncovered set of literal patterns
Issues #16289 and #15713 are proof that the pattern match checker did
an unsound job of estimating the value set abstraction corresponding to
the uncovered set.
The reason is that the fix from #11303 introducing `NLit` was
incomplete: The `LitCon` case desugared to `Var` rather than `LitVar`,
which would have done the necessary case splitting analogous to the
`ConVar` case.
This patch rectifies that by introducing the fresh unification variable
in `LitCon` in value abstraction position rather than pattern postition,
recording a constraint equating it to the constructor expression rather
than the literal. Fixes #16289 and #15713.

Fix #16518 with some more kind-splitting smarts
This patch corrects two simple oversights that led to #16518:
1. `HsUtils.typeToLHsType` was taking visibility into account in the
`TyConApp` case, but not the `AppTy` case. I've factored out the
visibility-related logic into its own `go_app` function and now
invoke `go_app` from both the `TyConApp` and `AppTy` cases.
2. `Type.fun_kind_arg_flags` did not properly split kinds with
nested `forall`s, such as
`(forall k. k -> Type) -> (forall k. k -> Type)`. This was simply
because `fun_kind_arg_flags`'s `FunTy` case always bailed out and
assumed all subsequent arguments were `Required`, which clearly
isn't the case for nested `forall`s. I tweaked the `FunTy` case
to recur on the result kind.

Tweak error messages for narrowly-kinded assoc default decls
This program, from #13971, currently has a rather confusing error
message:
```hs
class C a where
type T a :: k
type T a = Int
```
```
• Kind mis-match on LHS of default declaration for ‘T’
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
It's not at all obvious why GHC is complaining about the LHS until
you realize that the default, when printed with
`-fprint-explicit-kinds`, is actually `type T @{k} @* a = Int`.
That is to say, the kind of `a` is being instantiated to `Type`,
whereas it ought to be a kind variable. The primary thrust of this
patch is to weak the error message to make this connection
more obvious:
```
• Illegal argument ‘*’ in:
‘type T @{k} @* a = Int’
The arguments to ‘T’ must all be type variables
• In the default type instance declaration for ‘T’
In the class declaration for ‘C’
```
Along the way, I performed some code cleanup suggested by @rae in
https://gitlab.haskell.org/ghc/ghc/issues/13971#note_191287. Before,
we were creating a substitution from the default declaration's type
variables to the type family tycon's type variables by way of
`tcMatchTys`. But this is overkill, since we already know (from the
aforementioned validity checking) that all the arguments in a default
declaration must be type variables anyway. Therefore, creating the
substitution is as simple as using `zipTvSubst`. I took the
opportunity to perform this refactoring while I was in town.
Fixes #13971.

Generate straightline code for inline array allocation
GHC has an optimization for allocating arrays when the size is
statically known -- it'll generate the code allocating and initializing
the array inline (instead of a call to a procedure from
`rts/PrimOps.cmm`).
However, the generated code uses a loop to do the initialization. Since
we already check that the requested size is small (we check against
`maxInlineAllocSize`), we can generate faster straightline code instead.
This brings about 15% improvement for `newSmallArray#` in my testing and
slightly simplifies the code in GHC.

Fix #16500: look for interface files in -hidir flag in OneShot mode
We are currently ignoring options set in the hiDir field of hsc_dflags
when looking for interface files while compiling in OneShot mode. This
is inconsistent with the behaviour of other directory redirecting fields
(such as objectDir or hieDir). It is also inconsistent with the
behaviour of compilation in CompManager mode (a.k.a `ghc --make`) which
looks for interface files in the directory set in hidir flag. This
changes Finder.hs so that we use the value of hiDir while looking for
interface in OneShot mode.

Make `singleConstructor` cope with pattern synonyms
Previously, `singleConstructor` didn't handle singleton `COMPLETE` sets
of a single pattern synonym, resulting in incomplete pattern warnings
in #15753.
This is fixed by making `singleConstructor` (now named
`singleMatchConstructor`) query `allCompleteMatches`, necessarily making
it effectful. As a result, most of this patch is concerned with
threading the side-effect through to `singleMatchConstructor`.
Unfortunately, this is not enough to completely fix the original
reproduction from #15753 and #15884, which are related to function
applications in pattern guards being translated too conservatively.

codegen: fix memset unroll for small bytearrays, add 64-bit sets
Fixes #16052
When the offset in `setByteArray#` is statically known, we can provide
better alignment guarantees then just 1 byte.
Also, memset can now do 64-bit wide sets.
The current memset intrinsic is not optimal however and can be
improved for the case when we know that we deal with
(baseAddress at known alignment) + offset
For instance, on 64-bit
`setByteArray# s 1# 23# 0#`
given that bytearray is 8 bytes aligned could be unrolled into
`movb, movw, movl, movq, movq`; but currently it is
`movb x23` since alignment of 1 is all we can embed into MO_Memset op.

Hadrian: fix library install paths in bindist Makefile (#16498)
GHC now works out-of-the-box (i.e. without any wrapper script) by
assuming that @bin@ and @lib@ directories sit next to each other. In
particular, its RUNPATH uses $ORIGIN-based relative path to find the
libraries.
However, to be good citizens we want to support the case where @bin@ and
@lib@ directories (respectively BINDIR and LIBDIR) don't sit next to
each other or are renamed. To do that the install script simply creates
GHC specific @bin@ and @lib@ siblings directories into:
LIBDIR/ghc-VERSION/{bin,lib}
Then it installs wrapper scripts into BINDIR that call the appropriate
programs into LIBDIR/ghc-VERSION/bin/.
The issue fixed by this patch is that libraries were not installed into
LIBDIR/ghc-VERSION/lib but directly into LIBDIR.

Use ghc-prim < 0.7, not <= 0.6.1, as upper version bounds
Using `ghc-prim <= 0.6.1` is somewhat dodgy from a PVP point of view,
as it makes it awkward to support new minor releases of `ghc-prim`.
Let's instead use `< 0.7`, which is the idiomatic way of expressing
PVP-compliant upper version bounds.

all in all, this change paves the way towards a lot of future further
improvements in how GHC handles floating point computations, along with
making the native code gen more accessible to a larger pool of contributors.

Hadrian: add a --test-accept/-a flag, to mimic 'make accept'
When -a or --test-accept is passed, and if one runs the 'test' target, then
any test failing because of mismatching output and which is not expected to
fail will have its expected output adjusted by the test driver, effectively
considering the new output correct from now on.
When this flag is passed, hadrian's 'test' target becomes sensitive to the
PLATFORM and OS environment variable, just like the Make build system:
- when the PLATFORM env var is set to "YES", when accepting a result, accept it
for the current platform;
- when the OS env var is set to "YES", when accepting a result, accept it
for all wordsizes of the current operating system.
This can all be combined with `--only="..."` and `TEST="..." to only accept
the new output of a subset of tests.

gitlab: Don't run lint-submods job on Marge branches
This broke Marge by creating a second pipeline (consisting of only the
`lint-submods` job). Marge then looked at this pipeline and concluded
that CI for her merge branch passed. However, this is ignores the fact
that the majority of the CI jobs are triggered on `merge_request` and
are therefore in another pipeline.

Add a safeguard to Core Lint
Lint returns a pair (Maybe a, WarnsAndErrs). The Maybe monad
allows to handle an unrecoverable failure.
In case of such a failure, the error should be added to the second
component of the pair. If this is not done, Lint will silently
accept bad programs. This situation actually happened during
development of linear types. This adds a safeguard.

GHCi: fix load order of .ghci files
Directives in .ghci files in the current directory ("local .ghci")
can be overridden by global files. Change the order in which the
configs are loaded: global and $HOME/.ghci first, then local.
Also introduce a new field to GHCiState to control whether local
.ghci gets sourced or ignored. This commit does not add a way to
set this value (a subsequent commit will add this), but the .ghci
sourcing routine respects its value.

GHCi: add 'local-config' setting
Add the ':set local-config { source | ignore }' setting to control
whether .ghci file in current directory will be sourced or not. The
directive can be set in global config or $HOME/.ghci, which are
processed before local .ghci files.
The default is "source", preserving current behaviour.

asm-emit-time IND_STATIC elimination
When a new closure identifier is being established to a
local or exported closure already emitted into the same
module, refrain from adding an IND_STATIC closure, and
instead emit an assembly-language alias.
Inter-module IND_STATIC objects still remain, and need to be
addressed by other measures.
Binary-size savings on nofib are around 0.1%.

Introduce MonadP, make PV a newtype
Previously we defined type PV = P,
this had the downside that if we wanted to change PV,
we would have to modify P as well.
Now PV is free to evolve independently from P.
The common operations addError, addFatalError, getBit, addAnnsAt,
were abstracted into a class called MonadP.
