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

this adds a new flag.

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.

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.

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.

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.

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.
