Otherwise we can end up with an argument frame size that is not a multiple of stack slot size, which is very awkward. This fixes PR20547, which was a bug in x86_64 Sys V vararg handling. However, it's much easier to test this with x86 callee-cleanup functions, which previously ended in "retl $6" instead of "retl $8". This does affect behavior of all backends, but it presumably fixes the same bug in all of them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214980 91177308-0d34-0410-b5e6-96231b3b80d8
