openat/fstatat/unlinkat/dup are now used in the recent release of the
`directory` and `file-io` packages.
As such, these functions are (indirectly) used in the following tests
one we'll bump the `directory` submodule (see !13122):
- openFile008
- jsOptimizer
- T20509

The primary reason for this bump is to fix the warning from `ghc-pkg
check`:
```
Warning: include-dirs: /data/home/ubuntu/.ghcup/ghc/9.6.2/lib/ghc-9.6.2/lib/../lib/aarch64-linux-ghc-9.6.2/directory-1.3.8.1/include doesn't exist or isn't a directory
```
This also requires adding the `file-io` package as a boot library (which
is discussed in #25145)

We are producing bindists where the target triple is
aarch64-alpine-linux
when it should be
aarch64-unknown-linux
This is because the bootstrapped compiler originally set the target
triple to `aarch64-alpine-linux` which is when propagated forwards by
setting `bootstrap_target` from the bootstrap compiler target.
In order to break this chain we explicitly specify build/host/target for
aarch64-alpine.
This requires a new configure flag `--enable-ignore-` which just
switches off a validation check that the target platform of the
bootstrap compiler is the same as the build platform. It is the same,
but the name is just wrong.
These commits can be removed when the bootstrap compiler has the correct
target triple (I looked into patching this on ci-images, but it looked
hard to do correctly as the build/host platform is not in the settings
file).
Fixes #25200

This is a reinterpretation of GHC Proposal #409 that avoids a breaking
change introduced in fa0dbaca6c "Implements the Exportable Named Default proposal"
Consider a module M that has no explicit export list:
module M where
default (Rational)
Should it export the default (Rational)?
The proposal says "yes", and there's a test case for that:
default/DefaultImport04.hs
However, as it turns out, this change in behavior breaks existing
programs, e.g. the colour-2.3.6 package can no longer be compiled,
as reported in #25206.
In this patch, we make implicit exports of defaults conditional on
the NamedDefaults extension. This fix is unintrusive and compliant
with the existing proposal text (i.e. it does not require a proposal
amendment). Should the proposal be amended, we can go for a simpler
solution, such as requiring all defaults to be exported explicitly.
Test case: testsuite/tests/default/T25206.hs

The lazy structure (a list) in a strict field in `DmdType` is not fully
forced which leads to a very large thunk build-up.
It seems there is likely still more work to be done here as it seems we
may be trading space usage for work done. For now, this is the right
choice as rather than using all the memory on my computer, compilation
just takes a little bit longer.

Fixes #25211
When linking bytecode for TH from interface core bindings with
`-fprefer-byte-code`, foreign sources are loaded from the interface as
well and compiled to object code in an ad-hoc manner.
The results are then loaded by the interpreter, whose way may differ
from the current build's target way.
This patch ensures that foreign objects are compiled with the
interpreter's way.

This commit adds extra logic when looking up a record constructor.
If GHC.Rename.Env.lookupOccRnConstr returns a TyCon (as it may, due to
the logic explained in Note [Pattern to type (P2T) conversion]),
we emit an error saying that the data constructor is not in scope.
This avoids the compiler falling over shortly thereafter, in the call to
'lookupConstructorInfo' inside 'GHC.Rename.Env.lookupRecFieldOcc',
because the record constructor would not have been a ConLike.

When there are multiple threads they can race to create a temporary
file, in some situations the thread will create ghc_1.c and in some it
will create ghc_2.c. This filename ends up in the debug info for object
files after compiling a C file, therefore contributes to object
nondeterminism.
In order to fix this we store a prefix in `TmpFs` which serves to
namespace temporary files. The prefix is populated from the counter in
TmpFs when the TmpFs is forked. Therefore the TmpFs must be forked
outside the thread which consumes it, in a deterministic order, so each
thread always receives a TmpFs with the same prefix.
This assumes that after the initial TmpFs is created, all other TmpFs
are created from forking the original TmpFs. Which should have been try
anyway as otherwise there would be file collisions and non-determinism.
Fixes #25224

This is an unfortunate consequence of two mechanisms:
* GHC provides (possibly-empty) lists of names
* The functions that retrieve those names are not equipped to do error
reporting, and thus accept these lists at face value. They will have
to be attached an effect for error reporting in a later refactoring

There is one tricky aspect with wired-in packages where the boot package
is built with `-this-unit-id ghc` but the dependency is reported as
`-package-id ghc-9.6...`. This has never been fixed in GHC as the
situation of loading wired-in packages into the multi-repl seems like
quite a niche feature that is always just easier to workaround.

There have recently been some determinism issues with the simplifier and
documentation. We enable more things to test in the ABI test to check
that we produce interface files deterministically.

Before unarisation we may have code like:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
\u []
case (# |_| #) [GHC.Types.(##)] of sat_sAw [Occ=Once1] {
__DEFAULT -> Test.D [GHC.Types.True sat_sAw];
};
After unarisation we get:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
{} \u [] Test.D [GHC.Types.True 2#];
Notice that it's still an Updatable closure for no reason anymore. This
patch transforms appropriate StgRhsClosures into StgRhsCons after
unarisation, allowing these closures to be statically allocated. Now we
get the expected:
Test.foo :: Test.D
[GblId, Unf=OtherCon []] =
Test.D! [GHC.Types.True 2#];
Fix #25166
To avoid duplicating code, this patch refactors the mk(Top)StgRhs
functions and put them in a GHC.Stg.Make module alongside the new
mk(Top)StgRhsCon_maybe functions.
