; 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.
