S390: Optimize strchr and wcschr.
This patch provides optimized versions of strchr and wcschr with the z13 vector instructions. ChangeLog: * sysdeps/s390/multiarch/strchr-c.c: New File. * sysdeps/s390/multiarch/strchr-vx.S: Likewise. * sysdeps/s390/multiarch/strchr.c: Likewise. * sysdeps/s390/multiarch/wcschr-c.c: Likewise. * sysdeps/s390/multiarch/wcschr-vx.S: Likewise. * sysdeps/s390/multiarch/wcschr.c: Likewise. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add strchr and wcschr functions. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc test for strchr, wcschr. * string/strchr.c (STRCHR): Define and use macro. * benchtests/bench-wcschr.c: New File. * benchtests/Makefile (wcsmbs-bench): Add wcschr.
