/* Define this so that we can deal with a testcase like:
char foo __attribute__ ((mode (SI)));
then compiled with -mabi=64 and -mint64. We have no
32-bit type at that point and so the default case
always fails. Instead of special casing everything
it's easier to accept SImode in this function and
then punt to the default which will work for all
of the cases where we deal with TARGET_64BIT, etc. */
