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