split affine_transform on VNNI as well ``` LLR: 2.93 (-2.94,2.94) <0.00,2.00> Total: 184544 W: 47990 L: 47474 D: 89080 Ptnml(0-2): 551, 20238, 50206, 20698, 579 ``` Torom measured ``` sf_base = 2538696 +/- 2915 (95%) sf_test = 2546510 +/- 3011 (95%) diff = 7814 +/- 4146 (95%) speedup = 0.30782% +/- 0.163% (95%) ``` I get something similar. The benefit would be larger if we ever decide to further increase the L2 size I think closes https://github.com/official-stockfish/Stockfish/pull/6683 No functional change
