58e6cd4bcb x86: Move strlen SSE2 implementation to multiarch/strlen-sse2.S 
This commit doesn't affect libc.so.6, its just housekeeping to prepare
for adding explicit ISA level support.

Tested build on x86_64 and x86_32 with/without multiarch.

afc6e4328f x86: Put wcs{n}len-sse4.1 in the sse4.1 text section 
Previously was missing but the two implementations shouldn't get in
the sse2 (generic) text section.

a0db678071 x86-64: Move strlen.S to multiarch/strlen-vec.S 
Since strlen.S contains SSE2 version of strlen/strnlen and SSE4.1
version of wcslen/wcsnlen, move strlen.S to multiarch/strlen-vec.S
and include multiarch/strlen-vec.S from SSE2 and SSE4.1 variants.
This also removes the unused symbols, __GI___strlen_sse2 and
__GI___wcsnlen_sse4_1.

d4cc385c6e x86-64: Move wcsnlen.S to multiarch/wcsnlen-sse4_1.S 
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.
