Refine stat based reductions This patch separates stat based reductions for quiet moves in case of being in check and in case of not being in check. We will be using sum of first continuation history and main history (similar to movepicker) instead of statScore for the first case. passed STC https://tests.stockfishchess.org/tests/view/5ff87b2f6019e097de3ef09b LLR: 2.93 (-2.94,2.94) {-0.25,1.25} Total: 63992 W: 5887 L: 5678 D: 52427 Ptnml(0-2): 201, 4561, 22305, 4686, 243 passed LTC https://tests.stockfishchess.org/tests/view/5ff8b6206019e097de3ef0b2 LLR: 2.94 (-2.94,2.94) {0.25,1.25} Total: 81216 W: 3127 L: 2880 D: 75209 Ptnml(0-2): 46, 2544, 35176, 2801, 41 closes https://github.com/official-stockfish/Stockfish/pull/3293 bench 4395984
