  Log Message:
  -----------
  AMDGPU/GlobalISel: Directly diagnose return value use for FP atomics

Emit an error if the return value is used on subtargets that do not
support them. Previously we were falling back to the DAG on selection
failure, where it would emit this error and then fail again.
