Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7

This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and
Core i7.  It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and
up to 1X on Core i7.  It also improves memmove by up to 3X on Atom, up to
4X on Core 2 and up to 2X on Core i7.
