I've actually been thinking that the builtin is so weird that
we shouldn't do things this way at all.
We jump through a hoop with __builtin_stack_alloc, and then we
jump through a hoop with DECL_DEFER_OUTPUT in allocating the
variable at rtl time. Why in the world aren't we just
representing this as __builtin_alloca and normal indirection?
