Clarify the mapping of files to queenside This patch replaces the obscure expressions mapping files ABCDEFGH to ABCDDCBA by explicite calls to an auxiliary function: old: f = min(f, ~f) new: f = map_to_queenside(f) We used the Golbolt web site (https://godbolt.org) to check that the current code for the auxiliary function is optimal. STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 30292 W: 6756 L: 6651 D: 16885 http://tests.stockfishchess.org/tests/view/5d8676720ebc5971531d6aa1 Achieved with a bit of help from Sopel97, snicolet and vondele, thanks everyone! Closes https://github.com/official-stockfish/Stockfish/pull/2325 No functional change
