0a806311 - AMDGPU: Ensure both wavesize features are not set (#159234)

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.
