The ifunc handling for rawmemchr is adjusted in order to omit ifunc
variants if those will never be used as the minimum architecture level
already supports newer CPUs by default.
Glibc internal calls will then also use the "newer" ifunc variant.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove rawmemchr variants.
* sysdeps/s390/Makefile (sysdep_routines): Add rawmemchr variants.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Refactor ifunc handling for rawmemchr.
* sysdeps/s390/multiarch/rawmemchr-c.c: Move to ...
* sysdeps/s390/rawmemchr-c.c: ... here and adjust ifunc handling.
* sysdeps/s390/multiarch/rawmemchr-vx.S: Move to ...
* sysdeps/s390/rawmemchr-vx.S: ... here and adjust ifunc handling.
* sysdeps/s390/multiarch/rawmemchr.c: Move to ...
* sysdeps/s390/rawmemchr.c: ... here and adjust ifunc handling.
* sysdeps/s390/ifunc-rawmemchr.h: New file.
