S390: Optimize strncat wcsncat.
This patch provides optimized versions of strncat and wcsncat with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strncat-c.c: New File. * sysdeps/s390/multiarch/strncat-vx.S: Likewise. * sysdeps/s390/multiarch/strncat.c: Likewise. * sysdeps/s390/multiarch/wcsncat-c.c: Likewise. * sysdeps/s390/multiarch/wcsncat-vx.S: Likewise. * sysdeps/s390/multiarch/wcsncat.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strncat and wcsncat functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strncat, wcsncat. * wcsmbs/wcsncat.c (WCSNCAT): Define and use macro. * string/test-strncat.c: Add wcsncat support. * wcsmbs/test-wcsncat.c: New File. * wcsmbs/Makefile (strop-tests): Add wcsncat. * benchtests/bench-strncat.c: Add wcsncat support. * benchtests/bench-wcsncat.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcsncat.
