Piotr Padlewski 698667025a Handle invariant.group.barrier in BasicAA ... Summary: llvm.invariant.group.barrier returns pointer that mustalias pointer it takes. It can't be marked with `returned` attribute, because it would be remove easily. The other reason is that only Alias Analysis can know about this, because if any other pass would know it, then the result would be replaced with it's argument, which would be invalid. We can think about returned pointer as something that mustalias, but it doesn't have to be bitwise the same as the argument.
