The idea was to avoid misaligning the stack when __force_align_arg_pointer__
is not present, but not sure if we still care about such ancient compilers.
And yes, in such a case the places where we intentionally misalign the stack
(in kernel32 for example) are probably more critical. I'll leave the decision
up to you. ;)
