Ling Ma 05f3633da4 Improve 64bit memcpy performance for Haswell CPU with AVX instruction 
In this patch we take advantage of HSW memory bandwidth, manage to
reduce miss branch prediction by avoiding using branch instructions and
force destination to be aligned with avx instruction.

The CPU2006 403.gcc benchmark indicates this patch improves performance
from 2% to 10%.
