Refactor king ring calculation Compute the "double protection by pawns" expression only once in initialize(), instead of once for each piece in the piece loop. Passed STC http://tests.stockfishchess.org/tests/view/5c1506380ebc5902ba11f3b4 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 9494 W: 2191 L: 2045 D: 5258 Inspired by Nick Pelling's test http://tests.stockfishchess.org/tests/view/5c144d110ebc5902ba11e4af and an older test of mine http://tests.stockfishchess.org/tests/view/5c0402810ebc5902bcee1fc8 Non functional change.
