IBM zSystems: Optimize vec_cmpge followed by vec_sel
A vec_cmpge produces a negation. Replace this negation by swapping the two
selection choices of a vec_sel based on the result of the vec_cmpge.
gcc/ChangeLog:
* config/s390/vx-builtins.md: New vsel pattern.
gcc/testsuite/ChangeLog:
* gcc.target/s390/vector/vec-cmpge.c: New test.
