S390: Optimize strcspn and wcscspn.
This patch provides optimized versions of strcspn and wcscspn with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strcspn-c.c: New File. * sysdeps/s390/multiarch/strcspn-vx.S: Likewise. * sysdeps/s390/multiarch/strcspn.c: Likewise. * sysdeps/s390/multiarch/wcscspn-c.c: Likewise. * sysdeps/s390/multiarch/wcscspn-vx.S: Likewise. * sysdeps/s390/multiarch/wcscspn.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strcspn and wcscspn functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strcspn, wcscspn. * wcsmbs/wcscspn.c: Use WCSCSPN if defined. * string/test-strcspn.c: Add wcscspn support. * wcsmbs/test-wcscspn.c: New File. * wcsmbs/Makefile (strop-tests): Add wcscspn. * benchtests/bench-strcspn.c: Add wcscspn support. * benchtests/bench-wcscspn.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcscspn.
