Commit ID ea6220f3813e5b76b444a02905eaf2c556bdb368

This commit enables a mixed bench, to improve CI and allow for PGO (profile-build) of the NNUE part of the code. Joint work gvreuls / vondele * Download the default NNUE net in AppVeyor * Download net in travis CI `make net` * Adjust tests to cover more archs, speedup instrumented testing * Introduce 'mixed' bench as default, with further options: classical, NNUE, mixed. mixed (default) and NNUE require the default net to be present, which can be obtained with ``` make net ``` Further examples (first is equivalent to `./stockfish bench`): ``` ./stockfish bench 16 1 13 default depth mixed ./stockfish bench 16 1 13 default depth classical ./stockfish bench 16 1 13 default depth NNUE ``` The net is now downloaded automatically if needed for `profile-build` (usual `build` works fine without net present) PGO gives a nice speedup on fishtest: passed STC: LLR: 2.93 (-2.94,2.94) {-0.50,1.50} Total: 3360 W: 469 L: 343 D: 2548 Ptnml(0-2): 20, 246, 1030, 356, 28 https://tests.stockfishchess.org/tests/view/5f31b5499081672066537569 passed LTC: LLR: 2.97 (-2.94,2.94) {0.25,1.75} Total: 8824 W: 609 L: 502 D: 7713 Ptnml(0-2): 8, 430, 3438, 519, 17 https://tests.stockfishchess.org/tests/view/5f31c87b908167206653757c closes https://github.com/official-stockfish/Stockfish/pull/2931 fixes https://github.com/official-stockfish/Stockfish/issues/2907 requires fishtest updates before commit Bench: 4290577
