Add TT prefetching support TT.retrieve() is the most time consuming function because almost always involves a very slow RAM access. TT table is so big that is never cached. This patch prefetches TT data just after a move is done, so that subsequent TT.retrieve will be very fast. Profiling with VTune shows that TT:retrieve() times are almost cutted in half ! No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
