Optimize the most common update accumalator cases w/o tiling In the most common case where we only update a single state it's faster to not use temporary accumulation registers and tiling. (Also includes a couple of small cleanups.) passed STC https://tests.stockfishchess.org/tests/view/651918e3cff46e538ee0023b LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 34944 W: 8989 L: 8687 D: 17268 Ptnml(0-2): 88, 3743, 9512, 4037, 92 A simpler version https://tests.stockfishchess.org/tests/view/65190dfacff46e538ee00155 also passed but this version is stronger still https://tests.stockfishchess.org/tests/view/6519b95fcff46e538ee00fa2 closes https://github.com/official-stockfish/Stockfish/pull/4816 No functional change
