S390: Optimize strrchr and wcsrchr.
This patch provides optimized versions of strrchr and wcsrchr with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strrchr-c.c: New File. * sysdeps/s390/multiarch/strrchr-vx.S: Likewise. * sysdeps/s390/multiarch/strrchr.c: Likewise. * sysdeps/s390/multiarch/wcsrchr-c.c: Likewise. * sysdeps/s390/multiarch/wcsrchr-vx.S: Likewise. * sysdeps/s390/multiarch/wcsrchr.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strrchr and wcsrchr functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strrchr, wcsrchr. * benchtests/bench-wcsrchr.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcsrchr.
