    M llvm/test/CodeGen/X86/atomic32.ll

  Log Message:
  -----------
  [LegalizeTypes] Teach BitcastToInt_ATOMIC_SWAP to only create FP16_TO_FP when called from PromoteFloatResult.

There's also a call from SoftenFloatResult that should not be promoted.

The change test case would fail with the new RUN line prior to
this change.
