Disable unfolding sharing for interface files with core definitions

Ticket #22807 pointed out that the RHS sharing was not compatible with
-fignore-interface-pragmas because the flag would remove unfoldings from
identifiers before the `extra-decls` field was populated.

For the 9.6 timescale the only solution is to disable this sharing,
which will make interface files bigger but this is acceptable for the
first release of `-fwrite-if-simplified-core`.

For 9.8 it would be good to fix this by implementing #20056 due to the
large number of other bugs that would fix.

I also improved the error message in tc_iface_binding to avoid the "no match
in record selector" error but it should never happen now as the entire
sharing logic is disabled.

Also added the currently broken test for #22807 which could be fixed by
!6080

Fixes #22807

gitlab-ci: Eliminate redundant ghc --info output

Previously ci.sh would emit the output of `ghc --info` every time it ran
when using the nix toolchain. This produced a significant amount of
noise.

See #22861.

Windows: Remove mingwex dependency

The clang based toolchain uses ucrt as its math library
and so mingwex is no longer needed.  In fact using mingwex
will cause incompatibilities as the default routines in both
have differing ULPs and string formatting modifiers.

During interactive linking, GHCi couldn't find the following symbol:
  templatezmhaskell_LanguageziHaskellziTHziLibziInternal_stringL_closure
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session.  Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please report this as a GHC bug:

linker: Fix BFD import libraries

This commit fixes the BFD style import library support in the runtime
linker.  This was accidentally broken during the refactoring to clang
and went unnoticed because clang itself is unable to generate the BFD
style import libraries.

With this change we can not link against both GCC or Clang produced
libraries again and intermix code produced by both compilers.

Fix CallerCC potentially shadowing other cost centres.

Add a CallerCC cost centre flavour for cost centres added by the
CallerCC pass. This avoids potential accidental shadowing between
CCs added by user annotations and ones added by CallerCC.

Revert "Use fix-sized bit-fiddling primops for fixed size boxed types"

This reverts commit 4512ad2d6a8e65ea43c86c816411cb13b822f674.

This was never applied to master/9.6 originally.

Minor refactor

* Introduce refactorDupsOn f = refactorDups (comparing f)
* Make mkBigTupleCase and coreCaseTuple monadic.
  Every call to those functions was preceded by calling newUniqueSupply.
* Use mkUserLocalOrCoVar, which is equivalent to combining
  mkLocalIdOrCoVar with mkInternalName.
