Doesn't help.  The bug happens while we're still using the virtual
registers, so we haven't gotten to the point where
STACK_POINTER_OFFSET would be used.  Unless I'm misunderstanding how
that part of the code works, which is likely at this point anyway ;-)

Besides, the xstormy16 doesn't set it, so it's zero, which seems like
the right number anyway.
