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. * sysdeps/x86_64/multiarch/mempcpy-ssse3-back.S: Likewise. * sysdeps/x86_64/multiarch/mempcpy-ssse3.S: Likewise.
