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