S390: Use cu21 instruction for converting from utf16 to utf8.
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 cu21 instruction. ChangeLog: * sysdeps/s390/utf8-utf16-z9.c (__to_utf8_loop_vx_cu): Use vector and cu21 instruction. * sysdeps/s390/multiarch/utf8-utf16-z9.c: Add __to_utf8_loop_vx_cu in ifunc resolver.
