This MR fixes the bug exposed by #24676. The problem was that
quickLookArg was trying to avoid calling tcInstFun unnecessarily; but
it was in fact necessary. But that in turn forced me into a
significant refactoring, putting more fields into EValArgQL.
Highlights: see Note [Quick Look overview] in GHC.Tc.Gen.App
* Instantiation variables are now distinguishable from ordinary
unification variables, by level number = QLInstVar. This is
treated like "level infinity". See Note [The QLInstVar TcLevel]
in GHC.Tc.Utils.TcType.
* In `tcApp`, we don't track the instantiation variables in a set Delta
any more; instead, we just tell them apart by their level number.
* EValArgQL now much more clearly captures the "half-done" state
of typechecking an argument, ready for later resumption.
See Note [Quick Look at value arguments] in GHC.Tc.Gen.App
* Elminated a bogus (never used) fast-path in
GHC.Tc.Utils.Instantiate.instCallConstraints
See Note [Possible fast path for equality constraints]
Many other small refactorings.

The main payload of this patch is
* Prioritise nominal equalities in the constraint solver. This
ameliorates the incompleteness of solving for representational
constraints over newtypes: see #24887.
See (EX2) in Note [Decomposing newtype equalities] in
GHC.Tc.Solver.Equality
In doing this patch I tripped over some other things that I refactored:
* Move `isCoVarType` from `GHC.Core.Type` to `GHC.Core.Predicate`
where it seems more at home.
* Clarify the "rewrite role" of a constraint. I was very puzzled
about what the role of, say `(Eq a)` might be, but see the new
Note [The rewrite-role of a constraint].
In doing so I made predTypeEqRel crash when given a non-equality.
Usually it expects an equality; but it was being mis-used for
the above rewrite-role stuff.

This MR was triggered by #24868, but I found a number of bugs
and infelicities in type-tidying as I went along. Highlights:
* Fix to #24868 is in GHC.Tc.Errors.report_unsolved: avoid
using the OccNames of /bound/ variables when tidying /free/
variables; see the call to `tidyAvoiding`. That avoid the
gratuitous renaming which was the cause of #24868. See
Note [tidyAvoiding] in GHC.Core.TyCo.Tidy
* Refactor and document the tidying of open types.
See GHC.Core.TyCo.Tidy
Note [Tidying open types]
Note [Tidying is idempotent]
* Tidy the coercion variable in HoleCo. That's important so
that tidied types have tidied kinds.
* Some small renaming to make things consistent. In particular
the "X" forms return a new TidyEnv. E.g.
tidyOpenType :: TidyEnv -> Type -> Type
tidyOpenTypeX :: TidyEnv -> Type -> (TidyEnv, Type)

This commit introduces the RTS flag `--read-tix-file=<yes|no>` which
controls whether a preexisting .tix file is read in at the beginning
of a program run. The default is currently `--read-tix-file=yes` but
will change to `--read-tix-file=no` in a future release of GHC. For
this reason, whenever a .tix file is read in a warning is emitted to
stderr. This warning can be silenced by explicitly passing the
`--read-tix-file=yes` option. Details can be found in the GHC proposal
cited below.
Users can query whether this flag has been used with the help of the
module `GHC.RTS.Flags`. A new field `readTixFile` was added to the
record `HpcFlags`.
These changes have been discussed and approved in

As a `ModIface` often contains duplicated values that are not
necessarily shared, we improve sharing by serialising the `ModIface`
to an in-memory byte array. Serialisation uses deduplication tables, and
deserialisation implicitly shares duplicated values.
This helps reducing the peak memory usage while compiling in
`--make` mode. The peak memory usage is especially smaller when
generating interface files with core expressions
(`-fwrite-if-simplified-core`).
On agda, this reduces the peak memory usage:
* `2.2 GB` to `1.9 GB` for a ghci session.
On `lib:Cabal`, we report:
* `570 MB` to `500 MB` for a ghci session
* `790 MB` to `667 MB` for compiling `lib:Cabal` with ghc
There is a small impact on execution time, around 2% on the agda code
base.

To reduce memory usage of `ModIface`, we serialise `ModIface` to an
in-memory byte array, which implicitly shares duplicated values.
This serialised byte array can be reused to avoid work when we actually
write the `ModIface` to disk.
We introduce a new field to `ModIface` which allows us to save the byte
array, and write it direclty to disk if the `ModIface` wasn't changed
after the initial serialisation.
This requires us to change absolute offsets, for example to jump to the
deduplication table for `Name` or `FastString` with relative offsets, as
the deduplication byte array doesn't contain header information, such as
fingerprints.
To allow us to dump the binary blob to disk, we need to replace all
absolute offsets with relative ones.
We introduce additional helpers for `ModIface` binary serialisation, which
construct relocatable binary blobs. We say the binary blob is relocatable,
if the binary representation can be moved and does not contain any
absolute offsets.
Further, we introduce new primitives for `Binary` that allow to create
relocatable binaries, such as `forwardGetRel` and `forwardPutRel`.

-------------------------
These metric increases may look bad, but they are all completely benign,
we simply allocate 1 MB per module for `shareIface`. As this allocation
is quite quick, it has a negligible impact on run-time performance.
In fact, the performance difference wasn't measurable on my local
machine. Reducing the size of the pre-allocated 1 MB buffer avoids these
test failures, but also requires us to reallocate the buffer if the
interface file is too big. These reallocations *did* have an impact on
performance, which is why I have opted to accept all these metric
increases, as the number of allocated bytes is merely a guidance.
This 1MB allocation increase causes a lot of tests to fail that
generally have a low allocation number. E.g., increasing from 40MB to
41MB is a 2.5% increase.
In particular, the tests T12150, T13253-spj, T18140, T18304, T18698a,
T18923, T20049, T24582, T5837, T6048, and T9961 only fail on i386-darwin
job, where the number of allocated bytes seems to be lower than in other
jobs.
The tests T16875 and T18698b fail on i386-linux for the same reason.

This MR tackles #24623 and #23113
The main change is to give a clearer notion of "worker/wrapper arity", esp
for join points. See GHC.Core.Opt.DmdAnal
Note [Worker/wrapper arity and join points]
This Note is a good summary of what this MR does:
(1) The "worker/wrapper arity" of an Id is
* For non-join-points: idArity
* The join points: the join arity (Id part only of course)
This is the number of args we will use in worker/wrapper.
See `ww_arity` in `dmdAnalRhsSig`, and the function `workWrapArity`.
(2) A join point's demand-signature arity may exceed the Id's worker/wrapper
arity. See the `arity_ok` assertion in `mkWwBodies`.
(3) In `finaliseArgBoxities`, do trimBoxity on any argument demands beyond
the worker/wrapper arity.
(4) In WorkWrap.splitFun, make sure we split based on the worker/wrapper
arity (re)-computed by workWrapArity.

This commit enables some extensions and GHC flags in the cabal file in a way
that allows us to reduce the amount of prologuing on top of each file.
We also prefix the usage of some List functions that removes ambiguity
when they are also exported from the Prelude, like foldl'.
In general, this has the effect of pointing out more explicitly
that a linked list is used.

When matching a template variable to an expression, we check that it
has the same type as the matched expression. But if the variable `f` has
type `A -> B` while the expression `e` has type `A %1 -> B`, the match was
previously rejected.
A principled solution would have `f` substituted by `\(%Many x) -> e
x` or some other appropriate coercion. But since linearity is not
properly checked in Core, we can be cheeky and simply ignore
multiplicity while matching. Much easier.
This has forced a change in the linter which, when `-dlinear-core-lint`
is off, must consider that `a -> b` and `a %1 -> b` are equal. This is
achieved by adding an argument to configure the behaviour of
`nonDetCmpTypeX` and modify `ensureEqTys` to call to the new behaviour
which ignores multiplicities when comparing two `FunTy`.
Fixes #24725.

This MR speeds up type equality, triggered by perf regressions that
showed up when fixing #24725 by parameterising type equality over
whether to ignore multiplicity.
The changes are:
* Do not use `nonDetCmpType` for type /equality/. Instead use a specialised
type-equality function, which we have always had!
`nonDetCmpType` remains, but I did not invest effort in refactoring
or optimising it.
* Type equality is parameterised by
- whether to expand synonyms
- whether to respect multiplicities
- whether it has a RnEnv2 environment
In this MR I systematically specialise it for static values of these
parameters. Much more direct and predictable than before. See
Note [Specialising type equality]
* We want to avoid comparing kinds if possible. I refactored how this
happens, at least for `eqType`.
See Note [Casts and coercions in type comparison]
* To make Lint fast, we want to avoid allocating a thunk for <msg> in
ensureEqTypes ty1 ty2 <msg>
because the test almost always succeeds, and <msg> isn't needed.

After #22229 had been fixed, we can finally derive the `Lift` instance for the
TH AST, as proposed by Ryan Scott in
https://mail.haskell.org/pipermail/libraries/2015-September/026117.html.
Fixes #14030, #14296, #21759 and #24560.
The residency of T24471 increases by 13% because we now load `AnnLookup`
from its interface file, which transitively loads the whole TH AST.
Unavoidable and not terrible, I think.
Metric Increase:

If a user has configured CDPATH on their system then `cd lib` may change
into an unexpected directory during the installation process.
If you write `cd ./lib` then it will not consult `CDPATH` to determine
what you mean.
I have added a check on ghcup-ci to verify that the bindist installation
works in this situation.

The pervasive usage of DynFlags (the parsed command-line options passed
to ghc) blurs the border between different components of Haddock, and
especially those that focus solely on printing text on the screen.
In order to improve the understanding of the real dependencies of a
function, the pretty-printer options are made concrete earlier in the
pipeline instead of late when pretty-printing happens.
This also has the advantage of clarifying which functions actually
require DynFlags for purposes other than pretty-printing, thus making
the interactions between Haddock and GHC more understandable when
exploring the code base.

It is non-obvious whether the toolchain configuration should use
full-paths to tools or simply their names. In addressing #24574, we've
decided to prefer executable names over paths, ultimately, because the
bindist configure script already does this, thus is the default in ghcs
out there.
Updates the in-tree configure script to prefer tool names
(`AC_CHECK_TOOL` rather than `AC_PATH_TOOL`) and `ghc-toolchain` to
ignore the full-path-result of `findExecutable`, which it previously
used over the program name.
This change doesn't undo the fix in bd92182cd56140ffb2f68ec01492e5aa6333a8fc
because `AC_CHECK_TOOL` still takes into account the target triples,
unlike `AC_CHECK_PROG/AC_PATH_PROG`.

LlvmTarget was being set and substituted in the in-tree configure, but
not in the configure shipped in the bindist.
We want to set the LlvmTarget to the canonical LLVM name of the platform
that GHC is targetting.
Currently, that is going to be the boostrapped llvm target (hence the
code which sets LlvmTarget=bootstrap_llvm_target).

`compareLength xs n` is a safer and faster alternative to `compare (length xs) n`.
The latter would force and traverse the entire spine (potentially diverging),
while the former traverses as few elements as possible.
The implementation is carefully designed to maintain as much laziness as possible.

- Without TNTC (tables-next-to-code), we must be careful to not
duplicate labels in pprNatCmmDecl. Especially, as a CmmProc is
identified by the label of its entry block (and not of its info
table), we can't reuse the same label to delimit the block end and the
proc end.
- We generate debug infos from Cmm blocks. However, when
asm-shortcutting is enabled, some blocks are dropped at the asm
codegen stage and some labels in the DebugBlocks become missing.
We fix this by filtering the generated debug-info after the asm
codegen to only keep valid infos.
Also add some related documentation.

addr2Int# and int2Addr# were marked as deprecated with the introduction
of the OCaml code generator (1dfaee318171836b32f6b33a14231c69adfdef2f)
due to its use of tagged integers. However, this backend has long
vanished and `base` has all along been using `addr2Int#` in the Show
instance for Ptr.
While it's unlikely that we will have another backend which has tagged
integers, we may indeed support platforms which have tagged pointers.
Consequently we undeprecate the operations but warn the user that the
operations may not be portable.
