S390: Optimize strncpy and wcsncpy.
This patch provides optimized versions of strncpy and wcsncpy with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strncpy-vx.S: New File. * sysdeps/s390/multiarch/strncpy.c: Likewise. * sysdeps/s390/multiarch/wcsncpy-c.c: Likewise. * sysdeps/s390/multiarch/wcsncpy-vx.S: Likewise. * sysdeps/s390/multiarch/wcsncpy.c: Likewise. * sysdeps/s390/s390-32/multiarch/strncpy.c: Likewise. * sysdeps/s390/s390-64/multiarch/strncpy.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strncpy and wcsncpy functions. * wcsmbs/wcsncpy.c: Use WCSNCPY if defined. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strncpy, wcsncpy. * string/test-strncpy.c: Add wcsncpy support. * wcsmbs/test-wcsncpy.c: New File. * wcsmbs/Makefile (strop-tests): Add wcsncpy. * benchtests/bench-strncpy.c: Add wcsncpy support. * benchtests/bench-wcsncpy.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcsncpy
