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

[Eli Friedman via Phabricator via llvm-commits]

It looks like this transform destroys stack traces on non-x86 platforms.  That technically isn't wrong, I guess, but it seems unfriendly (for example, LLVM produces a stack trace on an assertion failure).
