s390: testsuite: Fix bitops-{1,2}.c and andc-splitter-2.c
After r16-2649-g0340177d54d tests fail for
gcc.target/s390/arch13/bitops-{1,2}.c since sign extends in conjunction
with (subreg (not a)) are folded, now. That is, of course, wanted.
Since the original tests were about 32-bit operations, circumvent the
sign extend by not returning a value but rather writing it to memory.
Similar for andc-splitter-2.c sign extends are folded there, too. Since
the test is not about 32- or 64-bit adjust the scan assembler directives
only.
gcc/testsuite/ChangeLog:
* gcc.target/s390/arch13/bitops-1.c: Do not return a 32bit value
but write it to memory.
* gcc.target/s390/arch13/bitops-2.c: Ditto.
* gcc.target/s390/md/andc-splitter-2.c: Adjust scan assembler
directive because sign extends are folded, now.
