target-supports.exp (check_effective_target_vect_aligned_arrays): New procedure to check if arrays are naturally aligned to the vector alignment...

        * lib/target-supports.exp (check_effective_target_vect_aligned_arrays):
        New procedure to check if arrays are naturally aligned to the vector
        alignment boundary.
        * gcc.dg/vect/pr25413a.c: Do not include stdarg.h.  Use __SIZE_TYPE__
        in size_t typedef.  Adjust tree dump scan results according to
        vect_aligned_arrays target check.
        * gcc.dg/vect/pr25413.c: Adjust tree dump scan results according to
        vect_aligned_arrays target check.
        * gcc.dg/vect/pr31699.c: Ditto.
