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

The architecture specific string.h had a typo, which leads to ommiting the
inline version in this file if __USE_STRING_INLINES is defined.
Tested this inline version by tweaking test-strcmp.c.

ChangeLog:

	* sysdeps/s390/multiarch/strcmp-vx.S: New File.
	* sysdeps/s390/multiarch/strcmp.c: Likewise.
	* sysdeps/s390/multiarch/wcscmp-c.c: Likewise.
	* sysdeps/s390/multiarch/wcscmp-vx.S: Likewise.
	* sysdeps/s390/multiarch/wcscmp.c: Likewise.
	* sysdeps/s390/s390-32/multiarch/strcmp.c: Likewise.
	* sysdeps/s390/s390-64/multiarch/strcmp.c: Likewise.
	* sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strcmp and
	wcscmp functions.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add ifunc test for strcmp, wcscmp.
	* string/strcmp.c (STRCMP): Define and use macro.
	* benchtests/bench-wcscmp.c: New File.
	* benchtests/Makefile (wcsmbs-bench): Add wcscmp.
	* sysdeps/s390/bits/string.h: Fix typo: _HAVE_STRING_ARCH_strcmp
	instead of _HAVE_STRING_ARCH_memchr.
