I already tried this out some years ago and I'm still doing this, I'm sure
others did/do too. But I did not find a significant improvement of the move
ordering, e.g. some minor changes to the history heuristic could easily have a
much bigger effect. But it does not hurt performance, so I did not remove the
code.
