I don't think it's worth keeping `-Wreturn-std-move` around if the only time it ever fires is when returning a `volatile`-qualified local variable; it certainly does not pull its weight if it only diagnoses that situation. I'm happy with losing the diagnostic for that case now, especially if we intend to remove the warning entirely as a follow-up. (The changes to `co_return` are a bugfix, so that seems fine. I'm not going to ask for a test for that change; it seems preferable to leave that to D68845 <https://reviews.llvm.org/D68845> or wherever we properly implement the copy-elision rules for `co_return`.)
