Well, just before builtin expansion anyway. In many cases we
would be better off expanding to trees instead of rtl. Some
of them don't make sense to do that but...

Making the last parameter of stdarg a reference parameter might
solve it. Alternately, is the last parameter even used other
than for checking that it is in fact the last parameter? If not,
then the front end could do the error check and expand that
builtin right away.
