[llvm] r329287 - ARM: Do not spill CSR to stack on entry to noreturn functions

[Tim Northover via llvm-commits]

Well, I eventually managed to reproduce it but then noticed 2 things:

1. The bot magically fixed itself after what looks like a list of
unrelated commits (first green build after the failure is 9355).
2. Reverting the patch locally didn't fix the issue for me.

So I don't know what's going on but until I see firm evidence
otherwise I'm going to assume it wasn't this patch.

Cheers.

Tim.
