While you’re at it, could you fix the old AMDIL intrinsics too?

I don’t think these have been updated yet (although the old names still technically work)

llvm.AMDIL.abs -> llvm.AMDGPU.abs
llvm.AMDIL.clamp -> llvm.AMDGPU.clamp
llvm.AMDIL.fraction -> llvm.AMDGPU.fract
llvm.AMDIL.exp -> llvm.exp2
llvm.AMDIL.round.nearest -> llvm.rint
