@arsenm I'm also not sure which can be better solution. I can imagine these
approaches, but I'm not sure I prefer one of them:
- Modify ExpandIRInsts to always expand power-of-2 div/rem
- Handle power-of-2 expansion in AMDGPUISelLowering::LowerDIVREM
- Adjust MaxLegalDivRemBitWidth for AMDGPU at -O0
