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