S390: Refactor wcsnlen ifunc handling.
The ifunc handling for wcsnlen 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.
Glibc internal calls will use the "newer" ifunc variant.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove wcsnlen variants.
* sysdeps/s390/Makefile (sysdep_routines): Add wcsnlen variants.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Refactor ifunc handling for wcsnlen.
* sysdeps/s390/multiarch/wcsnlen-c.c: Move to ...
* sysdeps/s390/wcsnlen-c.c: ... here and adjust ifunc handling.
* sysdeps/s390/multiarch/wcsnlen-vx.S: Move to ...
* sysdeps/s390/wcsnlen-vx.S: ... here and adjust ifunc handling.
* sysdeps/s390/multiarch/wcsnlen.c: Move to ...
* sysdeps/s390/wcsnlen.c: ... here and adjust ifunc handling.
* sysdeps/s390/ifunc-wcsnlen.h: New file.
