Determine opposite colors mathematically This is a non-functional speed-up: master has to access SquareBB twice while this patch determines opposite_colors just using the values of the squares. It doesn't seem to change the overall speed of bench, but calling opposite_colors(...) 10 Million times: master: 39.4 seconds patch: 11.4 seconds. The only data point I have (other than my own tests), is a quite old failed STC test: LLR: -2.93 (-2.94,2.94) [-1.50,4.50] Total: 24308 W: 5331 L: 5330 D: 13647 Ptnml(0-2): 315, 2577, 6326, 2623, 289 http://tests.stockfishchess.org/tests/view/5e010256c13ac2425c4a9a67 Closes https://github.com/official-stockfish/Stockfish/pull/2498 No functional change
