Use common_parent_position hint also at PVNodes TT hits. Credits to Stefan Geschwentner (locutus2) showing that the hint is useful on PvNodes. In contrast to his test, this version avoids to use the hint when in check. I believe checking positions aren't good candidates for the hint because: - evasion moves are rather few, so a checking pos. has much less childs than a normal position - if the king has to move the NNUE eval can't use incremental updates, so the child nodes have to do a full refresh anyway.
