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

you might want to do something like highlight the arrows belonging to the same

When split sections is enabled, ensure -fsplit-sections is passed to
GHC as well when invoking GHC to compile C/C++; and pass
-ffunction-sections -fdata-sections to gcc/clang when compiling C/C++
with the hadrian Cc builder. Fixes #23381.

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.
Fixes #23381.

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.
