Commit ID 23c385ec36f9d5a9514ec5b0811ec99d08b45e90
Author MaximMolchanov

Affine transform refactoring. Reordered weights in such a way that accumulated sum fits to output. Weights are grouped in blocks of four elements because four int8 (weight type) corresponds to one int32 (output type). No horizontal additions. Grouped AVX512, AVX2 and SSSE3 implementations. Repeated code was removed. An earlier version passed STC: LLR: 2.97 (-2.94,2.94) {-0.25,1.25} Total: 15336 W: 1495 L: 1355 D: 12486 Ptnml(0-2): 44, 1054, 5350, 1158, 62 https://tests.stockfishchess.org/tests/view/5ff60e106019e097de3eefd5 Speedup depends on the architecture, up to 4% measured on a NNUE only bench. closes https://github.com/official-stockfish/Stockfish/pull/3287 No functional change
