Andrew Senkevich 8b4416d83c i386: memcpy functions with SSE2 unaligned load/store 
These new memcpy functions are the 32-bit version of x86_64 SSE2 unaligned
memcpy.  Memcpy average performace benefit is 18% on Silvermont, other
platforms also improved about 35%, benchmarked on Silvermont, Haswell, Ivy
Bridge, Sandy Bridge and Westmere, performance results attached in
