5d04e520c0 Don't count inreg params when mangling fastcall functions 
This is consistent with MSVC.

9688239469 Round up the size of byval arguments to MinAlign 
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.
