rs6000/test: Adjust pr104992.c with vect_int_mod [PR106516]
As PR106516 shows, we can get unexpected gimple outputs for
function thud on some target which supports modulus operation
for vector int. This patch introduces one effective target
vect_int_mod for it, then adjusts the test case with it.
PR testsuite/106516
gcc/testsuite/ChangeLog:
* gcc.dg/pr104992.c: Adjust with vect_int_mod.
* lib/target-supports.exp (check_effective_target_vect_int_mod): New
effective target.
