s390: Fix ICE in testcase pr89233
When using GNU vector extensions, an access outside of the vector size
caused an ICE on s390. Fix this by aligning with the vec_extract
builtin, i.e., computing constant index modulo number of lanes.
Fixes testcase gcc.target/s390/pr89233.c.
gcc/ChangeLog:
* config/s390/vector.md: (*vec_extract) Fix.
