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