Optimize affine transform for SSSE3 and higher targets. A non-functional speedup. Unroll the loops going over the output dimensions in the affine transform layers by a factor of 4 and perform 4 horizontal additions at a time. Instead of doing naive horizontal additions on each vector separately use hadd and shuffling between vectors to reduce the number of instructions by using all lanes for all stages of the horizontal adds. passed STC of the initial version: LLR: 2.95 (-2.94,2.94) {-0.25,1.25} Total: 17808 W: 1914 L: 1756 D: 14138 Ptnml(0-2): 76, 1330, 5948, 1460, 90 https://tests.stockfishchess.org/tests/view/5f9d516f6a2c112b60691da3 passed STC of the final version after cleanup: LLR: 2.95 (-2.94,2.94) {-0.25,1.25} Total: 16296 W: 1750 L: 1595 D: 12951 Ptnml(0-2): 72, 1192, 5479, 1319, 86 https://tests.stockfishchess.org/tests/view/5f9df5776a2c112b60691de3 closes https://github.com/official-stockfish/Stockfish/pull/3203 No functional change
