IBM Z: Fix PR96456
The testcase failed because our backend refuses to generate vector
compare instructions for signaling operators with -fno-trapping-math
-fno-finite-math-only.
gcc/ChangeLog:
PR target/96456
* config/s390/s390.h (TARGET_NONSIGNALING_VECTOR_COMPARE_OK): New
macro.
* config/s390/vector.md (vcond_comparison_operator): Use new macro
for the check.
gcc/testsuite/ChangeLog:
PR target/96456
* gcc.target/s390/pr96456.c: New test.
