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.
