ghc-the-library: Retain cafs in both static in dynamic builds.
We use keepCAFsForGHCi.c to force -fkeep-cafs behaviour by using a
__attribute__((constructor)) function.
This broke for static builds where the linker discarded the object file
since it was not reverenced from any exported code. We fix this by
asserting that the flag is enabled using a function in the same module
as the constructor. Which causes the object file to be retained by the
linker, which in turn causes the constructor the be run in static builds.
This changes nothing for dynamic builds using the ghc library. But causes
static to also retain CAFs (as we expect them to).
Fixes #22417.

Handle `type data` properly in tyThingParent_maybe
Unlike most other data constructors, data constructors declared with `type data`
are represented in `TyThing`s as `ATyCon` rather than `ADataCon`. The `ATyCon`
case in `tyThingParent_maybe` previously did not consider the possibility of
the underlying `TyCon` being a promoted data constructor, which led to the
oddities observed in #22817. This patch adds a dedicated special case in
`tyThingParent_maybe`'s `ATyCon` case for `type data` data constructors to fix
these oddities.
Fixes #22817.

Fix two bugs in TypeData TH reification
This patch fixes two issues in the way that `type data` declarations were
reified with Template Haskell:
* `type data` data constructors are now properly reified using `DataConI`.
This is accomplished with a special case in `reifyTyCon`. Fixes #22818.
* `type data` type constructors are now reified in `reifyTyCon` using
`TypeDataD` instead of `DataD`. Fixes #22819.

Take account of loop breakers in specLookupRule
The key change is that in GHC.Core.Opt.Specialise.specLookupRule
we were using realIdUnfolding, which ignores the loop-breaker
flag. When given a loop breaker, rule matching therefore
looped infinitely -- #22802.
In fixing this I refactored a bit.
* Define GHC.Core.InScopeEnv as a data type, and use it.
(Previously it was a pair: hard to grep for.)
* Put several functions returning an IdUnfoldingFun into
GHC.Types.Id, namely
idUnfolding
alwaysActiveUnfoldingFun,
whenActiveUnfoldingFun,
noUnfoldingFun
and use them. (The are all loop-breaker aware.)

User's guide: Clarify overlapping instance candidate elimination
This commit updates the user's guide section on overlapping instance candidate
elimination to use "or" verbiage instead of "either/or" in regards to the
current pair of candidates' being overlappable or overlapping. "Either IX is
overlappable, or IY is overlapping" can cause confusion as it suggests "Either
IX is overlappable, or IY is overlapping, but not both".
This was initially discussed on this Discourse topic:

Improve exprOkForSpeculation for classops
This patch fixes #22745 and #15205, which are about GHC's
failure to discard unnecessary superclass selections that
yield coercions. See
GHC.Core.Utils Note [exprOkForSpeculation and type classes]
The main changes are:
* Write new Note [NON-BOTTOM_DICTS invariant] in GHC.Core, and
refer to it
* Define new function isTerminatingType, to identify those
guaranteed-terminating dictionary types.
* exprOkForSpeculation has a new (very simple) case for ClassOpId
* ClassOpId has a new field that says if the return type is
an unlifted type, or a terminating type.
This was surprisingly tricky to get right. In particular note
that unlifted types are not terminating types; you can write an
expression of unlifted type, that diverges. Not so for dictionaries
(or, more precisely, for the dictionaries that GHC constructs).

Cmm: track the type of global registers
This patch tracks the type of Cmm global registers. This is needed
in order to lint uses of polymorphic registers, such as SIMD vector
registers that can be used both for floating-point and integer values.
This changes allows us to refactor VanillaReg to not store VGcPtr,
as that information is instead stored in the type of the usage of the
register.

compiler: properly handle non-word-sized CmmSwitch scrutinees in the wasm NCG
Currently, the wasm NCG has an implicit assumption: all CmmSwitch
scrutinees are 32-bit integers. This is not always true; #22864 is one
counter-example with a 64-bit scrutinee. This patch fixes the logic by
explicitly converting the scrutinee to a word that can be used as a
br_table operand. Fixes #22871. Also includes a regression test.

Treat existentials correctly in dubiousDataConInstArgTys
Consider (#22849)
data T a where
MkT :: forall k (t::k->*) (ix::k). t ix -> T @k a
Then dubiousDataConInstArgTys MkT [Type, Foo] should return
[Foo (ix::Type)]
NOT [Foo (ix::k)]
A bit of an obscure case, but it's an outright bug, and the fix is easy.

Bump supported LLVM range from 10 through 15 to 11 through 16
LLVM 15 turns on the new pass manager by default, which we have yet to
migrate to so for new we pass the `-enable-new-pm-0` flag in our
llvm-passes flag.
LLVM 11 was the first version to support the `-enable-new-pm` flag so we
bump the lowest supported version to 11.
Our CI jobs are using LLVM 12 so they should continue to work despite
this bump to the lower bound.

CI: JavaScript backend runs testsuite
This MR runs the testsuite for the JS backend. Note that this is a
temporary solution until !9515 is merged.
Key point: The CI runs hadrian on the built cross compiler _but not_ on
the bindist.
Other Highlights:
- stm submodule gets a bump to mark tests as broken
- several tests are marked as broken or are fixed by adding more
- conditions to their test runner instance.
List of working commit messages:
CI: test cross target _and_ emulator
CI: JS: Try run testsuite with hadrian
JS.CI: cleanup and simplify hadrian invocation
use single bracket, print info
JS CI: remove call to test_compiler from hadrian
don't build haddock
JS: mark more tests as broken
Tracked in https://gitlab.haskell.org/ghc/ghc/-/issues/22576
JS testsuite: don't skip sum_mod test
Its expected to fail, yet we skipped it which automatically makes it
succeed leading to an unexpected success,
JS testsuite: don't mark T12035j as skip
leads to an unexpected pass
JS testsuite: remove broken on T14075
leads to unexpected pass
JS testsuite: mark more tests as broken
JS testsuite: mark T11760 in base as broken
JS testsuite: mark ManyUnbSums broken
submodules: bump process and hpc for JS tests
Both submodules has needed tests skipped or marked broken for th JS
backend. This commit now adds these changes to GHC.

Disable unfolding sharing for interface files with core definitions
Ticket #22807 pointed out that the RHS sharing was not compatible with
-fignore-interface-pragmas because the flag would remove unfoldings from
identifiers before the `extra-decls` field was populated.
For the 9.6 timescale the only solution is to disable this sharing,
which will make interface files bigger but this is acceptable for the
first release of `-fwrite-if-simplified-core`.
For 9.8 it would be good to fix this by implementing #20056 due to the
large number of other bugs that would fix.
I also improved the error message in tc_iface_binding to avoid the "no match
in record selector" error but it should never happen now as the entire
sharing logic is disabled.
Also added the currently broken test for #22807 which could be fixed by
!6080
Fixes #22807

This may be due to you not asking GHCi to load extra object files,

the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.

linker: Fix BFD import libraries
This commit fixes the BFD style import library support in the runtime
linker. This was accidentally broken during the refactoring to clang
and went unnoticed because clang itself is unable to generate the BFD
style import libraries.
With this change we can not link against both GCC or Clang produced
libraries again and intermix code produced by both compilers.

JS: replace "js" architecture with "javascript"
Despite Cabal supporting any architecture name, `cabal --check` only
supports a few built-in ones. Sadly `cabal --check` is used by Hackage
hence using any non built-in name in a package (e.g. `arch(js)`) is
rejected and the package is prevented from being uploaded on Hackage.
Luckily built-in support for the `javascript` architecture was added for
GHCJS a while ago. In order to allow newer `base` to be uploaded on
Hackage we make the switch from `js` to `javascript` architecture.
Fixes #22740.

Fix tyvar scoping within class SPECIALISE pragmas
Type variables from class/instance headers scope over class/instance
method type signatures, but DO NOT scope over the type signatures in
SPECIALISE and SPECIALISE instance pragmas.
The logic in GHC.Rename.Bind.rnMethodBinds correctly accounted for
SPECIALISE inline pragmas, but forgot to apply the same treatment
to method SPECIALISE pragmas, which lead to a Core Lint failure with
an out-of-scope type variable. This patch makes sure we apply the same
logic for both cases.

Refactor the simplifier a bit to fix #22761
The core change in this commit, which fixes #22761, is that
* In a Core rule, ru_rhs is always occ-analysed.
This means adding a couple of calls to occurAnalyseExpr when
building a Rule, in
* GHC.Core.Rules.mkRule
* GHC.Core.Opt.Simplify.Iteration.simplRules
But diagosing the bug made me stare carefully at the code of the
Simplifier, and I ended up doing some only-loosely-related refactoring.
* I think that RULES could be lost because not every code path
did addBndrRules
* The code around lambdas was very convoluted
It's mainly moving deck chairs around, but I like it more now.

RTS linker: Improve compatibility with NetBSD
1. Hint address to NetBSD mmap(2) has a different semantics from that of
Linux. When a hint address is provided, mmap(2) searches for a free
region at or below the hint but *never* above it. This means we can't
reliably search for free regions incrementally on the userland,
especially when ASLR is enabled. Let the kernel do it for us if we don't
care where the mapped address is going to be.
2. NetBSD not only hates to map pages as rwx, but also disallows to switch
pages from rw- to r-x unless the intention is declared when pages are
initially requested. This means we need a new MemoryAccess mode for
pages that are going to be changed to r-x.

Introduce warning for loopy superclass solve
Commit aed1974e completely re-engineered the treatment of loopy
superclass dictionaries in instance declarations. Unfortunately,
it has the potential to break (albeit in a rather minor way) user code.
To alleviate migration concerns, this commit re-introduces the old
behaviour. Any reliance on this old behaviour triggers a warning,
controlled by `-Wloopy-superclass-solve`. The warning text explains
that GHC might produce bottoming evidence, and provides a migration
strategy.
This allows us to provide a graceful migration period, alerting users
when they are relying on this unsound behaviour.

compiler: fix cost centre profiling breakage in wasm NCG due to incorrect register mapping
The wasm NCG used to map CCCS to a wasm global, based on the
observation that CCCS is a transient register that's already handled
by thread state load/store logic, so it doesn't need to be backed by
the rCCCS field in the register table.
Unfortunately, this is wrong, since even when Cmm execution hasn't
yielded back to the scheduler, the Cmm code may call enterFunCCS,
which does use rCCCS.
This breaks cost centre profiling in a subtle way, resulting in
inaccurate stack traces in some test cases. The fix is simple though:
just remove the CCCS mapping.

fix: Explicitly flush stdout on plugin
Because of #20791, the plugins tests often fail. This is a temporary
fix to stop the tests from failing due to unflushed outputs on windows
and the explicit flush should be removed when #20791 is fixed.

Don't generate datacon wrappers for `type data` declarations
Data constructor wrappers only make sense for _value_-level data constructors,
but data constructors for `type data` declarations only exist at the _type_
level. This patch does the following:
* The criteria in `GHC.Types.Id.Make.mkDataConRep` for whether a data
constructor receives a wrapper now consider whether or not its parent data
type was declared with `type data`, omitting a wrapper if this is the case.
* Now that `type data` data constructors no longer receive wrappers, there is a
spot of code in `refineDefaultAlt` that panics when it encounters a value
headed by a `type data` type constructor. I've fixed this with a special case
in `refineDefaultAlt` and expanded `Note [Refine DEFAULT case alternatives]`
to explain why we do this.
Fixes #22948.

Treat type data declarations as empty when checking pattern-matching coverage
The data constructors for a `type data` declaration don't exist at the value
level, so we don't want GHC to warn users to match on them.

Disallow `tagToEnum#` on `type data` types
We don't want to allow users to conjure up values of a `type data` type using
`tagToEnum#`, as these simply don't exist at the value level.

GHC proposal 496 - Nullary record wildcards
This patch implements GHC proposal 496, which allows record wildcards
to be used for nullary constructors, e.g.
data A = MkA1 | MkA2 { fld1 :: Int }
f :: A -> Int
f (MkA1 {..}) = 0
f (MkA2 {..}) = fld1
To achieve this, we add arity information to the record field
environment, so that we can accept a constructor which has no fields
while continuing to reject non-record constructors with more than 1
field. See Note [Nullary constructors and empty record wildcards],
as well as the more general overview in Note [Local constructor info in the renamer],
both in the newly introduced GHC.Types.ConInfo module.
Fixes #22161

rts: Fix `prompt#` when profiling is enabled

Fix ParallelListComp out of scope suggestion
This patch makes it so vars from one block of a parallel list
comprehension are not in scope in a subsequent block during type
