S390: Optimize strlen and wcslen.
This patch provides optimized versions of strlen and wcslen with the z13 vector instructions. The helper macro IFUNC_VX_IMPL is introduced and is used to register all __<func>_c() and __<func>_vx() functions within __libc_ifunc_impl_list() to the ifunc test framework. ChangeLog: * sysdeps/s390/multiarch/Makefile: New File. * sysdeps/s390/multiarch/strlen-c.c: Likewise. * sysdeps/s390/multiarch/strlen-vx.S: Likewise. * sysdeps/s390/multiarch/strlen.c: Likewise. * sysdeps/s390/multiarch/wcslen-c.c: Likewise. * sysdeps/s390/multiarch/wcslen-vx.S: Likewise. * sysdeps/s390/multiarch/wcslen.c: Likewise. * string/strlen.c (STRLEN): Define and use macro. * sysdeps/s390/multiarch/ifunc-impl-list.c (IFUNC_VX_IMPL): New macro function. (__libc_ifunc_impl_list): Add ifunc test for strlen, wcslen. * benchtests/Makefile (wcsmbs-bench): New variable. (string-bench-all): Added wcsmbs-bench. * benchtests/bench-wcslen.c: New File.
