re PR target/92904 (varargs for __int128 is placed at an unaligned location and uses movdqa for the load)

PR target/92904
* config/i386/i386.c (ix86_gimplify_va_arg): If need_intregs and
not need_temp, decrease alignment of the read because the GPR save
area only guarantees 8-byte alignment.

* gcc.c-torture/execute/pr92904.c: New test.
