Do more reductions for late quiet moves in case of consecutive fail highs. Idea of this patch can be described as following - in case we have consecutive fail highs and we reach late enough moves at root node probability of remaining quiet moves being able to produce even bigger value than moves that produced previous cutoff (so ones that should be high in move ordering but now they fail to produce beta cutoff because we actually reached high move count) should be quiet small so we can reduce them more. passed STC LLR: 2.94 (-2.94,2.94) {-0.25,1.25} Total: 53392 W: 5681 L: 5474 D: 42237 Ptnml(0-2): 214, 4104, 17894, 4229, 255 https://tests.stockfishchess.org/tests/view/5f88501adcdad978fe8c527e passed LTC LLR: 2.94 (-2.94,2.94) {0.25,1.25} Total: 59136 W: 2773 L: 2564 D: 53799 Ptnml(0-2): 30, 2117, 25078, 2300, 43 https://tests.stockfishchess.org/tests/view/5f884dbfdcdad978fe8c527a closes https://github.com/official-stockfish/Stockfish/pull/3184 Bench: 4066972
