[PATCH] D42898: Do not spill CSR to stack on entry to noreturn functions

[Tim Northover via Phabricator via llvm-commits]

I managed to track down the issue, and I think the patch needs to respect the "uwtable" attribute too (otherwise the tables produced are useless). So I've recommitted with that change applied; hopefully it'll stick this time.
