commit r16-2090-g32d41517c7276399e57b2b3f29e9790ae32d4883

s390: Split tests for 31bit support
The new vector pattern tests used int128 without guard. This causes
failure on 31bit targets. Split the tests such that the tests
requiring 128 bit support are only executed on targets supporting
them.

gcc/testsuite/ChangeLog:
* gcc.target/s390/vector/pattern-avg-1.c: Split test.
* gcc.target/s390/vector/pattern-mulh-1.c: Split test.
* gcc.target/s390/vector/pattern-avg-2.c: New test.
* gcc.target/s390/vector/pattern-mulh-2.c: New test.
