x86-64: Fold ifunc-sse4_1.h into wcsnlen.c
Since ifunc-sse4_1.h is included only by wcsnlen.c, we can fold it into wcsnlen.c. No code changes in wcsnlen.o. 2017-06-07 H.J. Lu <hongjiu.lu@intel.com> * sysdeps/x86_64/multiarch/ifunc-sse4_1.h: Removed and folded into ... * sysdeps/x86_64/multiarch/wcsnlen.c: Here. Don't include ifunc-sse4_1.h.
