Hans Wennborg ba9e1e6b25 Win64: Don't emit unwind info for "leaf" functions (PR30337) ...

According to MSDN (see the PR), functions which don't touch any callee-saved
registers (including %rsp) don't need any unwind info.

This patch makes LLVM not emit unwind info for such functions, to save
binary size.
