This patch adds an ifunc variant to use the cu instruction on arch12 CPUs. This new ifunc variant can be built if binutils support z13 vector instructions. At runtime, HWCAP_S390_VXE decides if we can use the cu41 instruction. ChangeLog: * sysdeps/s390/utf8-utf32-z9.c (__to_utf8_loop_vx_cu): Use vector and cu41 instruction. * sysdeps/s390/multiarch/utf8-utf32-z9.c: Add __to_utf8_loop_vx_cu in ifunc resolver.
