62a9aadd - [AMDGPU] Add optimization for llvm.amdgcn.wave.shuffle in uniform cases (#174795)

[AMDGPU] Add optimization for llvm.amdgcn.wave.shuffle in uniform cases (#174795) When the llvm.amdgcn.wave.shuffle intrinsic is called with a uniform Index operand, it is effectively the same as the llvm.amdgcn.readlane intrinsic. This change handles this situation and replaces it with the readlane intrinsic --------- Signed-off-by: Domenic Nutile <domenic.nutile@gmail.com>
