IIRC there is a x86 (enter leave?) that moves the top of the stack in a way
that can be undone. If that allows a non literal arguments, a pair of these
around the scope would do it.

offset = FP
offset += ENTER_META_DATA.sizeof
offset &= 0x0f
offset -= ENTER_META_DATA.sizeof

enter offset // push offset space and some metadata
..... scope
leave // pop it all off
