Fix LLVM vs Apple LLVM version numbering confusion, for $avx512ifma

Apple LLVM has a different version numbering scheme than upstream LLVM.
That makes for quite a bit of confusion.

https://en.wikipedia.org/wiki/Xcode#Toolchain_versions to the rescue,
they have collected quite a lot of useful data.

This change is concentrated around the `$avx512ifma` flag

Fixes #16670 for the master branch
