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.

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.

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.
