S390: Optimize strcpy and wcscpy.
This patch provides optimized versions of strcpy and wcscpy with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strcpy-vx.S: New File. * sysdeps/s390/multiarch/strcpy.c: Likewise. * sysdeps/s390/multiarch/wcscpy-c.c: Likewise. * sysdeps/s390/multiarch/wcscpy-vx.S: Likewise. * sysdeps/s390/multiarch/wcscpy.c: Likewise. * sysdeps/s390/s390-32/multiarch/strcpy.c: Likewise. * sysdeps/s390/s390-64/multiarch/strcpy.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strcpy and wcscpy functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strcpy, wcscpy. * benchtests/bench-wcscpy.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcscpy.
