  Log Message:
  -----------
  AMDGPU: Ensure both wavesize features are not set (#159234)

Make sure we cannot be in a mode with both wavesizes. This
prevents assertions in a future change. This should probably
just be an error, but we do not have a good way to report
errors from the MCSubtargetInfo constructor.
