configure: Rip out Solaris dyld check

Solaris 11 was released over a decade ago and, moreover, I doubt we have
any Solaris users

testsuite: Do not require CUSKs

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 115cd3c85a8 to work around the lack of CUSKs in GHC2021.

EPA: Simplify GHC/Parser.y comb2

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.

Fix deprecation warning when deprecated identifier is from another module

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

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.

Improve the situation with the stimes cycle

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.

Refactor Unique to be represented by Word64

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.

Reinstate untouchable variable error messages

This extra bit of information was accidentally being discarded after
a refactoring of the way we reported problems when unifying a type
variable with another type. This patch rectifies that.

configure: Drop Clang command from settings

Due to 01542cb7227614a93508b97ecad5b16dddeb6486 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.

driver: Fix -S with .cmm files

There was an oversight in the driver which assumed that you would always
produce a `.o` file when compiling a .cmm file.
