S390: Optimize memchr, rawmemchr and wmemchr.
This patch provides optimized versions of memchr, rawmemchr and wmemchr with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/memchr-vx.S: New File. * sysdeps/s390/multiarch/memchr.c: Likewise. * sysdeps/s390/multiarch/rawmemchr-c.c: Likewise. * sysdeps/s390/multiarch/rawmemchr-vx.S: Likewise. * sysdeps/s390/multiarch/rawmemchr.c: Likewise. * sysdeps/s390/multiarch/wmemchr-c.c: Likewise. * sysdeps/s390/multiarch/wmemchr-vx.S: Likewise. * sysdeps/s390/multiarch/wmemchr.c: Likewise. * sysdeps/s390/s390-32/multiarch/memchr.c: Likewise. * sysdeps/s390/s390-64/multiarch/memchr.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add memchr, wmemchr and rawmemchr functions. * sysdeps/s390/multiarch/ifunc-impl-list-common.c (__libc_ifunc_impl_list_common): Add ifunc test for memchr, rawmemchr and wmemchr. * wcsmbs/wmemchr.c: Use WMEMCHR if defined. * string/test-memchr.c: Add wmemchr support. * wcsmbs/test-wmemchr.c: New File. * wcsmbs/Makefile (strop-tests): Add wmemchr. * benchtests/bench-memchr.c: Add wmemchr support. * benchtests/bench-wmemchr.c: New File. * benchtests/Makefile (wcsmbs-bench): wmemchr.
