x86-64: Move wcsnlen.S to multiarch/wcsnlen-sse4_1.Shjl/avx2/fix
Since wcsnlen.S uses pminud which is the part of SSE4.1, move wcsnlen.S
to multiarch/wcsnlen-sse4_1.S.
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add
wcsnlen-sse4_1 and wcsnlen-c.
* sysdeps/x86_64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Test __wcsnlen_sse4_1 and
__wcsnlen_sse2.
* sysdeps/x86_64/multiarch/ifunc-sse4_1.h: New file.
* sysdeps/x86_64/multiarch/wcsnlen-c.c: Likewise.
* sysdeps/x86_64/multiarch/wcsnlen-sse4_1.S: Likewise.
* sysdeps/x86_64/multiarch/wcsnlen.c: Likewise.
* sysdeps/x86_64/wcsnlen.S: Removed.
