i386: Set cfun->machine->max_used_stack_alignment if needed
cfun->machine->max_used_stack_alignment is used to decide how stack frame
should be aligned. This is independent of any psABIs nor 32-bit vs 64-bit.
It is always safe to compute max_used_stack_alignment. We compute it only
if 128-bit aligned load/store may be generated on misaligned stack slot
which will lead to segfault.
