Thus we make `template-haskell` reinstallable and keep it as the public
API for Template Haskell.
All of the wired-in identifiers are moved to `ghc-internal`.
This necessitates also moving much of `ghc-boot-th` into `ghc-internal`.
These modules are then re-exported from `ghc-boot-th` and
`template-haskell`.
To avoid a dependency on `template-haskell` from `lib:ghc`, we instead
depend on the TH ASTs via `ghc-boot-th`.
As `template-haskell` no longer has special status, we can drop the
logic adding an implicit dependency on `template-haskell` when using TH.
We can also drop the `template-haskell-next` package, which was
previously used when bootstrapping.
When bootstrapping, we need to vendor the TH AST modules from
`ghc-internal` into `ghc-boot-th`. This is controlled by the `bootstrap`
cabal flag as before. See Note [Bootstrapping Template Haskell].
We split out a GHC.Internal.TH.Lift module resolving #24752.
This module is only built when not bootstrapping.
Resolves #24703

This patch fixes an unaligned load in nonmoving gc by ensuring the
closure address is properly untagged first before attempting to
prefetch its header. The unaligned load is reported by
UndefinedBehaviorSanitizer:
```
rts/sm/NonMovingMark.c:921:9: runtime error: member access within misaligned address 0x0042005f3a71 for type 'StgClosure' (aka 'struct StgClosure_'), which requires 8 byte alignment

^
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior rts/sm/NonMovingMark.c:921:9
```
This issue had previously gone unnoticed since it didn't really harm
runtime correctness, the invalid header address directly loaded from a
tagged pointer is only used as prefetch address and will not cause
segfaults. However, it still should be corrected because the prefetch
would be rendered useless by this issue, and untagging only involves a
single bitwise operation without memory access so it's cheap enough to
add.

It does not add diagrams for ArrowChoice for the time being, mainly because it's

When -fsplit-sections is passed to GHC, pass -ffunction-sections
-fdata-sections to gcc/clang when building C/C++. Previously,
-fsplit-sections was only respected by the NCG/LLVM backends, but not
the unregisterised backend; the GHC driver did not pass
-fdata-sections and -ffunction-sections to the C compiler, which
resulted in excessive executable sizes.

This patch removes special consideration for ArchWasm32 in
cmmDoCmmSwitchPlans, which means the compiler will now disable
cmmImplementSwitchPlans for wasm unreg backend, just like unreg
backend of other targets. We enabled it in the past to workaround some
compile-time panic in older versions of LLVM, but those panics are no
longer present, hence no need to keep this workaround.

hadrian may invoke findExecutable "" at run-time due to a certain
program is not found by configure script. Which is fine and
findExecutable is supposed to return Nothing in this case. However, on
Windows there's a directory bug that throws an exception (see
https://github.com/haskell/directory/issues/180), so we might as well
use a wrapper for findExecutable and handle exceptions gracefully.

When configure fails to find LLC/OPT/LLVMAS within supported version
range, it used to set "llc"/"opt"/"clang" as fallback values. This
behavior is particularly troublesome when the user has llc/opt/clang
with other versions in their PATH and run the testsuite, since hadrian
will incorrectly assume have_llvm=True and pass that to the testsuite
driver, resulting in annoying optllvm test failures (#23186). If
configure determines llc/opt/clang wouldn't work, then we shouldn't
pretend it'll work at all, and the bindist configure will invoke
FIND_LLVM_PROG check again at install time anyway.

2. Generated code got

This patch makes hadrian build in-tree GMP with the
--enable-alloca=malloc-notreentrant configure option. We will only
need malloc-reentrant when we have threaded RTS and SMP support on
wasm32, which will take some time to happen, before which we should
use malloc-notreentrant to avoid undesired runtime overhead.

For each module in a GHCi session, we keep alive one `ModLocation`.
A `ModLocation` is fairly inefficiently packed, as `String`s are
expensive in memory usage.
While benchmarking the agda codebase, we concluded that we keep alive
around 11MB of `FilePath`'s, solely retained by `ModLocation`.
We provide a more densely packed encoding of `ModLocation`, by moving
from `FilePath` to `OsPath`. Further, we migrate the full `Finder`
component to `OsPath` to avoid unnecessary transformations.
As the `Finder` component is well-encapsulated, this requires only a
minimal amount of changes in other modules.
We introduce pattern synonym for 'ModLocation' which maintains backwards
compatibility and avoids breaking consumers of 'ModLocation'.

We have formally dropped i386 windows support (#18487) a long time
ago. The stdcall foreign call convention is only used by i386 windows,
and the legacy logic around it is a significant maintenance burden for
future work that adds arm64 windows support (#24603). Therefore, this
patch removes stdcall support completely from the compiler as well as
the RTS (#24883):
- stdcall is still recognized as a FFI calling convention in Haskell
syntax. GHC will now unconditionally emit a warning
(-Wunsupported-calling-conventions) and treat it as ccall.
- Apart from minimum logic to support the parsing and warning logic,
all other code paths related to stdcall has been completely stripped
from the compiler.
- ghci only supports FFI_DEFAULT_ABI and ccall convention from now on.
- FFI foreign export adjustor code on all platforms no longer handles
the stdcall case and only handles ccall from now on.
- The Win32 specific parts of RTS no longer has special code paths for
stdcall.
This commit is the final nail on the coffin for i386 windows support.
Further commits will perform more housecleaning to strip the legacy
code paths and pave way for future arm64 windows support.

This patch adjusts test cases to handle the stdcall removal:
- Some stdcall usages are replaced with ccall since stdcall doesn't
make sense anymore.
- We also preserve some stdcall usages, and check in the expected
warning messages to ensure GHC always warn about stdcall usages
(-Wunsupported-calling-conventions) as expected.
- Error code testsuite coverage is slightly improved,
-Wunsupported-calling-conventions is now tested.
- Obsolete code paths related to i386 windows are also removed.

In pursuit of: #22736.
This MR moves ad-hoc symbols used throughout the js backend into a
single symbols file. Why? First, this cleans up the code by removing
ad-hoc strings created on the fly and therefore makes the code more
maintainable. Second, it makes it much easier to eventually type these
identifiers.

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)
