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