This adds testing infrastructure to ensure that changes in core libraries (e.g. `base` and `ghc-prim`) are caught in CI.

Previously the field used to filter the sub-declarations to show was rather ad-hoc and was only able to show at most one sub-declaration.

There was an oversight in the driver which assumed that you would always produce a `.o` file when compiling a .cmm file. Fixes #23610
-
Here we enable use of the testsuite driver's `--unexpected-output-dir` flag by CI, preserving the result as an artifact for use by users.
-
Here we introduce a new flag to the testsuite driver, --unexpected-output-dir=<dir>, which allows the user to ask the driver to preserve unexpected output from tests. The intent is for this to be used in CI to allow users to more easily fix unexpected platform-dependent output.

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. Fixes #23602

Due to 01542cb7 we no longer use the `runClang` function, and no longer need to configure into settings the Clang command. We used to determine options at runtime to pass clang when it was used as an assembler, but now that we configure at configure time we no longer need to.

In #22010 we established that Int was not always sufficient to store all the uniques we generate during compilation on 32-bit platforms. This commit addresses that problem by using Word64 instead of Int for uniques. The core of the change is in GHC.Core.Types.Unique and GHC.Core.Types.Unique.Supply. However, the representation of uniques is used in many other places, so those needed changes too. Additionally, the RTS has been extended with an atomic_inc64 operation. One major change from this commit is the introduction of the Word64Set and Word64Map data types. These are adapted versions of IntSet and IntMap from the containers package. These are planned to be upstreamed in the future. As a natural consequence of these changes, the compiler will be a bit slower and take more space on 32-bit platforms. Our CI tests indicate around a 5% residency increase.

Currently the Semigroup stimes cycle is resolved in GHC.Base by importing stimes implementations from a hs-boot file. Resolve the cycle using hs-boot files for required classes (Num, Integral) instead. Now stimes can be defined directly in GHC.Base, making inlining and specialization possible. This leads to some new boot files for `GHC.Num` and `GHC.Real`, the methods for those are only used to implement `stimes` so it doesn't appear that these boot files will introduce any new performance traps.

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.
-
Such warnings are highly dependent upon the toolchain, platform, and build configuration. It's simply too fragile to rely on these.
-
As noted in #23577, CentOS's ancient toolchain throws spurious missing-field-initializer warnings.

A stray 'Just' was being printed in the deprecation message. Fixes #23573

Use the HasLoc instance from Ast.hs to allow comb2 to work with anything with a SrcSpan This gets rid of the custom comb2A, comb2Al, comb2N functions, and removes various reLoc calls.

Its usefulness has long passed.

Numerous tests make use of CUSKs (complete user-supplied kinds), a legacy feature scheduled for deprecation. In order to proceed with the said deprecation, the tests have been updated to use SAKS instead (standalone kind signatures). This also allows us to remove the Haskell2010 language pragmas that were added in 115cd3c8 to work around the lack of CUSKs in GHC2021.
