S390: Refactor wcsrchr ifunc handling.
The ifunc handling for wcsrchr is adjusted in order to omit ifunc if the minimum architecture level already supports newer CPUs by default. Unfortunately the c ifunc variant can't be omitted at all as it is used by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcsrchr variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcsrchr variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcsrchr. * sysdeps/s390/multiarch/wcsrchr-c.c: Move to ... * sysdeps/s390/wcsrchr-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsrchr-vx.S: Move to ... * sysdeps/s390/wcsrchr-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsrchr.c: Move to ... * sysdeps/s390/wcsrchr.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcsrchr.h: New file.
