[PATCH] D72742: Don't assume promotable integers are zero/sign-extended already in x86-64 ABI.

I wrote some stuff on https://bugs.llvm.org/show_bug.cgi?id=44228, probably best to continue the discussion there. I really don't think we should take this patch -- at least not without reopening the ABI discussion first.
