Adjust singular LMR for positions seen in PV This patch continues work on altering search for ttPv nodes, using recent idea to alter it more in not PvNodes. Previous tweak based on this idea adjusted singularBeta - this one adjusts value of singularLMR, so they are both related to singular extension search. passed STC http://tests.stockfishchess.org/tests/view/5e700737e42a5c3b3ca2e659 LLR: 2.95 (-2.94,2.94) {-0.50,1.50} Total: 140608 W: 27053 L: 26659 D: 86896 Ptnml(0-2): 2425, 16337, 32439, 16625, 2478 passed LTC http://tests.stockfishchess.org/tests/view/5e7068eae42a5c3b3ca2e687 LLR: 2.94 (-2.94,2.94) {0.25,1.75} Total: 79318 W: 10463 L: 10064 D: 58791 Ptnml(0-2): 567, 7416, 23359, 7685, 632 closes https://github.com/official-stockfish/Stockfish/pull/2588 Bench: 4952322
