[PATCH 19/27] S390: Optimize strrchr and wcsrchr.

[Stefan Liebler <stli at linux dot vnet dot ibm dot com>]

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.
