Minor cleanup of search.cpp Four very minor edits. Note that tte->save() uses posKey and not pos.key() in other places. Originally I also added a futility_move_counts() function to make things more consistent with the futility_margin() and reduction() functions. But then razor_margin[] should probably also be turned into a function, etc. Maybe a good idea, maybe not. So I did not include it. Non functional change.
