[PATCH] D54516: [AMDGPU] Do not mark llvm.amdgcn.set.inactive as IntrNoMem

EarlyCSE does seem to common up in this situation. And, if I disable that, I get GVN commoning it up.

Nicolai, thanks for reminding me of the Mesa inline asm hack, which you have told me about before. I think my best short term solution is to use that same hack in my frontend when generating llvm.amdgcn.set.inactive. Could you point me at that hack again please?
