The type variables in the holes fit output from
`abstract_refinement_hole_fits` is quite sensitive to compiler
configuration. Specifically, a slight change in the inlining
behavior of `throw` changes type variable naming in `(>>=)` and a few
others.
Ideally we would make hole fits output more deterministic but in the
meantime we simply normalise this difference away as it not relevant
to the test's goal.

As noted in #25066, the exception backtrace proposal introduced a rather
subtle performance regression due to simplification producing Core which
the demand analyser concludes may diverge with a precise exception. The
nature of the problem is more completely described in the new Note
[Hiding precise exception signature in throw].
The (rather hacky) solution we use here hides the problematic
optimisation through judicious use of `noinline`. Ultimately however we
will want a more principled solution (e.g. #23847).

This patch fixes an unnoticed undefined behavior in the bytecode
interpreter. It can be caught by building `rts/Interpreter.c` with
`-fsanitize=pointer-overflow`, the warning message is something like:
```
rts/Interpreter.c:1369:13: runtime error: addition of unsigned offset to 0x004200197660 overflowed to 0x004200197658
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior rts/Interpreter.c:1369:13
rts/Interpreter.c:1265:13: runtime error: addition of unsigned offset to 0x004200197660 overflowed to 0x004200197658
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior rts/Interpreter.c:1265:13
rts/Interpreter.c:1645:13: runtime error: addition of unsigned offset to 0x0042000b22f8 overflowed to 0x0042000b22f0
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior rts/Interpreter.c:1645:13
```
Whenever we do something like `SpW(-1)`, the negative argument is
implicitly converted to an unsigned integer type and causes pointer
arithmetic overflow. It happens to be harmless for most targets since
overflowing would wrap the result to desired value, but it's still
coincidental and undefined behavior. Furthermore, it causes real
damage to the wasm backend, given clang-20 will emit invalid wasm code
that crashes at run-time for this kind of C code! (see
https://github.com/llvm/llvm-project/issues/108770)
The fix here is adding some explicit casts to ensure we always use the
signed `ptrdiff_t` type as right hand operand of pointer arithmetic.

Currently the ExecPage facility has two users:
* GHCi, for constructing info tables, and
* the adjustor allocation path
Despite neither of these have any spatial locality constraints ExecPage
was using the linker's `mmapAnonForLinker`, which tries hard to ensure
that mappings end up nearby the executable image. This makes adjustor
allocation needlessly subject to fragmentation concerns.
We now instead return less constrained mappings, improving the
robustness of the mechanism.
Addresses #25503.

Just like ghc-internal it will now use the @ProjectVersionForLib@ macro for versioning.
This means for ghc=9.10.1, ghc-experimental's version will be 9.1001.0 and so on.
This fixes #25289
