ghcup-metadata: Use dynamically linked alpine bindists

In theory these will work much better on alpine to allow people to build
statically linked applications there. We don't need to distribute a
statically linked application ourselves in order to allow that.

rts: Don't rely on initializers for sigaction_t

As noted in #23577, CentOS's ancient toolchain throws spurious
missing-field-initializer warnings.

hadrian: Don't treat -Winline warnings as fatal

Such warnings are highly dependent upon the toolchain, platform, and
build configuration. It's simply too fragile to rely on these.

hadrian: Only pass -Wno-nonportable-include-path on Darwin

This flag, which was introduced due to #17798, is only understood by
Clang and consequently throws warnings on platforms using gcc. Sadly,
there is no good way to treat such warnings as non-fatal with `-Werror`
so for now we simply make this flag specific to platforms known to use
Clang and case-insensitive filesystems (Darwin and Windows).

See #23577.

rts: Work around missing prototypes errors

Darwin's toolchain inexpliciably claims that `write_barrier` and friends
have declarations without prototypes, despite the fact that (a) they are
definitions, and (b) the prototypes appear only a few lines above. Work
around this by making the definitions proper prototypes.

Define FFI_GO_CLOSURES

The libffi shipped with Apple's XCode toolchain does not contain a
definition of the FFI_GO_CLOSURES macro, despite containing references
to said macro. Work around this by defining the macro, following the
model of a similar workaround in OpenJDK [1].

As debugTrace is a macro we must take care to ensure that
the fact is clear to the compiler lest we see warnings.

hadrian: Fix dependencies of docs:* rule

For the docs:* rule we need to actually build the package rather than
just the haddocks for the dependent packages. Therefore we depend on the
.conf files of the packages we are trying to build documentation for as
well as the .haddock files.

Fixes #23472

rts: Ensure that pinned allocations respect block size

Previously, it was possible for pinned, aligned allocation requests to
allocate beyond the end of the pinned accumulator block. Specifically,
we failed to account for the padding needed to achieve the requested
alignment in the "large object" check. With large alignment requests,
this can result in the allocator using the capability's pinned object
accumulator block to service a request which is larger than
`PINNED_EMPTY_SIZE`.

To fix this we reorganize `allocatePinned` to consistently account for
the alignment padding in all large object checks. This is a bit subtle
as we must handle the case of a small allocation request filling the
accumulator block, as well as large requests.

Fixes #23400.

Support large stack frames/offsets in GHCi bytecode interpreter

Bytecode instructions like PUSH_L (push a local variable) contain
an operand that refers to the stack slot. Before this patch, the
operand type was SmallOp (Word16), limiting the maximum stack
offset to 65535 words. This could cause compiler panics in some
cases (See #22888).

This patch changes the operand type for stack offsets from
SmallOp to Op, removing the stack offset limit.

Fixes #22888

Use generated src span for catch-all case of record selector functions

This fixes #23492. The problem was that we used the real source span
of the field declaration for the generated catch-all case in the
selector function, in particular in the generated call to
`recSelError`, which meant it was included in the HIE output. Using
`generatedSrcSpan` instead means that it is not included.
