Revert futility pruning patches reverts 09b6d28391cf582d99897360b225bcbbe38dd1c6 and dbd7f602d3c7622df294f87d7239b5aaf31f695f that significantly impact mate finding capabilities. For example on ChestUCI_23102018.epd, at 1M nodes, the number of mates found is nearly reduced 2x without these depth conditions: sf6 2091 sf7 2093 sf8 2107 sf9 2062 sf10 2208 sf11 2552 sf12 2563 sf13 2509 sf14 2427 master 1246 patched 2467 (script for testing at https://github.com/official-stockfish/Stockfish/files/6936412/matecheck.zip) closes https://github.com/official-stockfish/Stockfish/pull/3641 fixes https://github.com/official-stockfish/Stockfish/issues/3627 Bench: 5467570
