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