S390: Optimize memccpy.
This patch provides optimized versions of memccpy with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/memccpy-c.c: New File. * sysdeps/s390/multiarch/memccpy-vx.S: Likewise. * sysdeps/s390/multiarch/memccpy.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add memccpy functions. * sysdeps/s390/multiarch/ifunc-impl-list-common.c (__libc_ifunc_impl_list_common): Add ifunc test for memccpy. * string/memccpy.c: Use MEMCCPY if defined.
