    A llvm/test/CodeGen/AArch64/GlobalISel/select-fp-anyext-crash.ll

  Log Message:
  -----------
  [AArch64][GlobalISel] Fix crash when selecting an anyextending FP load.

We split anyext FP loads back into a regular load + extend, but when we do that
we need to ensure that some state about the instruction is updated to correctly
reflect the new reality.
