S390: Optimize strrchr and wcsrchr.
This patch provides optimized versions of strrchr and wcsrchr with the z13
vector instructions.

* 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.
