Combine last 3 add/remove operations https://tests.stockfishchess.org/tests/view/67ad587052879dfd14d7e8a5 LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 45856 W: 12177 L: 11855 D: 21824 Ptnml(0-2): 176, 4845, 12588, 5119, 200 The two most common cases are when added and removed counts are equal and when they are off by 1. When they are off by 1 we currently do a pass combining 2 and then an extra pass for the last 1. This patch does a single combined pass on the final 3 instead. Tested on top of the simplification in https://github.com/official-stockfish/Stockfish/pull/5901 closes https://github.com/official-stockfish/Stockfish/pull/5902 No functional change
