Make __memcpy_avx512_no_vzeroupper an alias

Since x86-64 memcpy-avx512-no-vzeroupper.S implements memmove, we can make
__memcpy_avx512_no_vzeroupper an alias of __memmove_avx512_no_vzeroupper
to reduce code size of libc.so.

	* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Remove
	memcpy-avx512-no-vzeroupper.
	* sysdeps/x86_64/multiarch/memcpy-avx512-no-vzeroupper.S: Renamed
	to ...
	* sysdeps/x86_64/multiarch/memmove-avx512-no-vzeroupper.S: This.
	(MEMCPY): Don't define.
	(MEMCPY_CHK): Likewise.
	(MEMPCPY): Likewise.
	(MEMPCPY_CHK): Likewise.
	(MEMPCPY_CHK): Renamed to ...
	(__mempcpy_chk_avx512_no_vzeroupper): This.
	(MEMPCPY_CHK): Renamed to ...
	(__mempcpy_chk_avx512_no_vzeroupper): This.
	(MEMCPY_CHK): Renamed to ...
	(__memmove_chk_avx512_no_vzeroupper): This.
	(MEMCPY): Renamed to ...
	(__memmove_avx512_no_vzeroupper): This.
	(__memcpy_avx512_no_vzeroupper): New alias.
	(__memcpy_chk_avx512_no_vzeroupper): Likewise.
