Improve multiPV mode Skip all moves during the Non-PV (zero-window) search which will be searched as PV moves later anyways. We also wake sure the moves will be reported to the GUI despite they're not being searched — some GUIs may get confused otherwise, and it would unnecessarily complicate the code. Tested with MultiPV=4 STC http://tests.stockfishchess.org/tests/view/5ce7137c0ebc5925cf070d69 LLR: 2.95 (-2.94,2.94) [0.50,4.50] Total: 8233 W: 3708 L: 3424 D: 1101 LTC http://tests.stockfishchess.org/tests/view/5ce798d60ebc5925cf071d17 LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 7369 W: 3197 L: 2911 D: 1261 Closes https://github.com/official-stockfish/Stockfish/pull/2163 No functional change.
