*	Added memcpy/memmove family optimized with AVX512 for KNL hardware.	Andrew Senkevich	2016-01-15	1	-0/+410
	Added AVX512 implementations of memcpy, mempcpy, memmove, memcpy_chk, mempcpy_chk, memmove_chk. It shows average improvement more than 30% over AVX versions on KNL hardware (performance results attached in the thread <https://sourceware.org/ml/libc-alpha/2016-01/msg00258.html>). * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Added new files. * sysdeps/x86_64/multiarch/ifunc-impl-list.c: Added new tests. * sysdeps/x86_64/multiarch/memcpy-avx512-no-vzeroupper.S: New file. * sysdeps/x86_64/multiarch/mempcpy-avx512-no-vzeroupper.S: Likewise. * sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S: Likewise. * sysdeps/x86_64/multiarch/memcpy.S: Added new IFUNC branch. * sysdeps/x86_64/multiarch/memcpy_chk.S: Likewise. * sysdeps/x86_64/multiarch/memmove.c: Likewise. * sysdeps/x86_64/multiarch/memmove_chk.c: Likewise. * sysdeps/x86_64/multiarch/mempcpy.S: Likewise. * sysdeps/x86_64/multiarch/mempcpy_chk.S: Likewise.
