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.

testsuite: Allow preservation of unexpected output
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.

Add warn_and_run test kind
This is a compile_and_run variant which also captures the GHC's
stderr. The warn_and_run name is best I can come up with,
as compile_and_run is taken.
This is useful specifically for testing warnings. We want to test that
when warning triggers, and it's not a false positive, i.e. that the
runtime behaviour is indeed "incorrect".
As an example a single test is altered to use warn_and_run

configure: Don't use ld.gold on i386
ld.gold appears to produce invalid static constructor tables on i386.
While ideally we would add an autoconf check to check for this
brokenness, sadly such a check isn't easy to compose. Instead to
summarily reject such linkers on i386.
Somewhat hackily closes #23579.

compiler: Fingerprint more code generation flags
Previously our recompilation check was quite inconsistent in its
coverage of non-optimisation code generation flags. Specifically, we
failed to account for most flags that would affect the behavior of
generated code in ways that might affect the result of a program's
execution (e.g. `-feager-blackholing`, `-fstrict-dicts`)
Closes #23369.

compiler: Record original thunk info tables on stack
Here we introduce a new code generation option, `-forig-thunk-info`,
which ensures that an `stg_orig_thunk_info` frame is pushed before every
update frame. This can be invaluable when debugging thunk cycles and
similar.
See Note [Original thunk info table frames] for details.
Closes #23255.
