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.

<no location info>: error:
GHC.ByteCode.Linker.lookupCE
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:

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.

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.

Previously the AtomicRead and AtomicWrite operations were emitted as
out-of-line calls. However, these tend to be very important for
performance, especially the RELAXED case (which only exists for
ThreadSanitizer checking).
Fixes #22115.
