S390: Move utf16-utf32-z9.c to multiarch folder and use s390_libc_ifunc_expr macro. The utf16-utf32-z9.c iconv module is using ifunc and thus the ifunc part should be in multiarch folder. Otherwise ifunc is used even if you configure with --disable-multi-arch. This patch moves the ifunc resolvers to the new file sysdeps/s390/multiarch/utf16-utf32-z9.c. The resolvers are now implemented with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc directly. The ifunc versions are implemented in sysdeps/s390/utf16-utf32-z9.c. Each version is only implemented if needed or supported. Therefore there is a block at beginning of the file which selects the versions which should be defined depending on support for multiarch, vector-support and used minimum architecture level. This block defines HAVE_[FROM|TO]_[C|VX] to 1 or 0. The code below is rearranged and surrounded by #if HAVE_[FROM|TO]_[C|VX] == 1. There is no functional change. ChangeLog: * sysdeps/s390/multiarch/utf16-utf32-z9.c: New File. * sysdeps/s390/utf16-utf32-z9.c: Move ifunc resolvers to multiarch folder and define ifunc versions depending on HAVE_[FROM|TO]_[C|VX]. (HAVE_FROM_C, HAVE_FROM_VX, HAVE_TO_C, HAVE_TO_VX, FROM_LOOP_DEFAULT, FROM_LOOP_C, FROM_LOOP_VX, TO_LOOP_DEFAULT, TO_LOOP_C, TO_LOOP_VX): New Define.

S390: Use cu24 instruction for converting from utf16 to utf32. This patch adds an ifunc variant to use the cu instruction on arch12 CPUs.
