I'll re-do this patch to unconditionally zero-extend for returns and also fix up the G_STORE legalisation to always zero-extend too. Given we don't have any target hooks that give us the information we need, let's go with just matching SelectionDAG behaviour?

As for the zeroext attributes, from what I can tell we've had the distinction between Darwin and non-Darwin with this since the beginning of the AArch64 target, which was contributed by @t.p.northover. I'd rather not be messing with that unless I have to.
