This reverts commit r214981. I'm not sure what I was thinking when I wrote this. Testing with MSVC shows that this function is mangled to '@f@8': int __fastcall f(int a, int b); llvm-svn: 220492

; Previously we would forget to align to stack slot alignment after placing a

; byval argument. Subsequent arguments would align themselves, but if it was
|
|
; the last argument, the argument size would not be a multiple of stack slot
|
|
; size. This resulted in retl $6 in callee-cleanup functions, as well as subtle

; varargs bugs.
