This patch achieves an improvement of 3-5%. It is useless to do binary searches and other fancy things if the function does a possibly quadratic memmove. memmove itself is a bottleneck because we know we are transferring 32-bit quantities, because we know in which direction they should be transferred, and on x86 because "rep movsb" is bad on many processors.
