Not always. Remember PR14498. Dale had to add this back in March,
because the gimplifier was seeing the VA_ARG_EXPR after the variable had
already been gimplified as a register.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14498 has a test case. We
really need to lower VA_ARG_EXPR. This is just too ugly.
