Clean SIMD code a bit Cleaner vector code structure in feature transformer. This patch just regroups the parts of the inner loop for each SIMD instruction set. Tested for non-regression: LLR: 2.96 (-2.94,2.94) <-2.50,0.50> Total: 115760 W: 9835 L: 9831 D: 96094 Ptnml(0-2): 326, 7776, 41715, 7694, 369 https://tests.stockfishchess.org/tests/view/60b96b39457376eb8bcaa26e It would be nice if a future patch could use some of the macros at the top of the file to unify the code between the distincts SIMD instruction sets (of course, unifying the Relu will be the challenge). closes https://github.com/official-stockfish/Stockfish/pull/3506 No functional change
