Description

AMDGPU should implement this optimization hook: https://github.com/llvm/llvm-project/blob/b333edd0d6da744c099ad3ff3b5fbd2d4e4dd45a/llvm/include/llvm/CodeGen/TargetLowering.h#L797

This is available on the SALU for i32 and i64 (s_andn2_b32 and s_andn2_b64). The implementation therefore should be approximately !N->isDivergent() && (N->getValueType() == i32 || i64).
