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