One instance of reductions array STC https://tests.stockfishchess.org/tests/view/6abc689cc109910452a9aa6d LLR: 2.93 (-2.94,2.94) <-1.75,0.25> Total: 144288 W: 36608 L: 36515 D: 71165 Ptnml(0-2): 189, 15260, 41141, 15377, 177 Use just one reductions array by all workers instead of separate instances. (Now possible since we don't depend on thread count any more) closes https://github.com/official-stockfish/Stockfish/pull/7205 No functional change
