(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.
