Ma, Ling fdf4289679 x86, mem: Don't implement forward memmove() as memcpy() 
memmove() allow source and destination address to be overlap, but
there is no such limitation for memcpy().  Therefore, explicitly
implement memmove() in both the forwards and backward directions, to
give us the ability to optimize memcpy().
