Auto merge of #45012 - Gankro:noalias, r=arielb1
Add -Zmutable-noalias flag We disabled noalias on mutable references a long time ago when it was clear that llvm was incorrectly handling this in relation to unwinding edges. Since then, a few things have happened: * llvm has cleaned up a bunch of the issues (I'm told) * we've added a nounwind codegen option As such, I would like to add this -Z flag so that we can evaluate if the codegen bugs still exist, and if this significantly affects the codegen of different projects, with an eye towards permanently re-enabling it (or at least making it a stable option).
