Implement x86-64 multiarch mempcpy in memcpy
Implement x86-64 multiarch mempcpy in memcpy to share most of code. It
reduces code size of libc.so.
[BZ #18858]
* sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Remove
mempcpy-ssse3, mempcpy-ssse3-back, mempcpy-avx-unaligned
and mempcpy-avx512-no-vzeroupper.
* sysdeps/x86_64/multiarch/memcpy-avx-unaligned.S (MEMPCPY_CHK):
New.
(MEMPCPY): Likewise.
* sysdeps/x86_64/multiarch/memcpy-avx512-no-vzeroupper.S
(MEMPCPY_CHK): New.
(MEMPCPY): Likewise.
* sysdeps/x86_64/multiarch/memcpy-ssse3-back.S (MEMPCPY_CHK): New.
(MEMPCPY): Likewise.
* sysdeps/x86_64/multiarch/memcpy-ssse3.S (MEMPCPY_CHK): New.
(MEMPCPY): Likewise.
* sysdeps/x86_64/multiarch/mempcpy-avx-unaligned.S: Removed.
* sysdeps/x86_64/multiarch/mempcpy-avx512-no-vzeroupper.S:
Likewise.
