More aggressive pruning the unlikely reference frames. Use (5/8)
when prune_comp_search_by_single_result is 1, use (6/8) when
prune_comp_search_by_single_result >= 2.

Tested foreman, city, student CIF (30 frames, bitrate=500, Speed 1),
average 5.2% speed up. AWCY results:
Speed 1: 0.03 PSNR loss
Speed 3: 0.05 PSNR loss
