Speedup KPK bitbase of 25% Change the way the index is coded so that now looping from 0 to IndexMax generates the pawns from RANK_7 down to RANK2. Becuase positions with pawns at RANK_7 are easily classified as wins/draws, this small trick allows to reduce the number of needed iterations from 30 down to 26! No functional change.
