S/390: z13 Change predicates of 128 bit add sub.
So far usage of 128 bit add/sub instruction was rejected if the second operand was a constant because the predicate rejected this. gcc/testsuite/ChangeLog: * gcc.target/s390/vector/int128-1.c: New test. gcc/ChangeLog: * config/s390/vector.md ("<ti*>add<mode>3", "<ti*>sub<mode>3"): Change the predicate of op2 from nonimmediate to general and let reload fix it if necessary.
