Adjust reductions based on the number of threads In lazySMP it makes sense to prune a little more, as multiple threads search wider. We thus increase the prefactor of the reductions slowly as a function of the threads. The prefactor of the log(threads) term is a parameter, this pull request uses 1/2 after testing. passed STC @ 8threads: LLR: 2.96 (-2.94,2.94) [0.50,4.50] Total: 118125 W: 23151 L: 22462 D: 72512 http://tests.stockfishchess.org/tests/view/5d8bbf4d0ebc59509180f217 passed LTC @ 8threads: LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 67546 W: 10630 L: 10279 D: 46637 http://tests.stockfishchess.org/tests/view/5d8c463b0ebc5950918167e8 passed ~LTC @ 14threads: LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 74271 W: 12421 L: 12040 D: 49810 http://tests.stockfishchess.org/tests/view/5d8db1f50ebc590f3beb24ef Note: A larger prefactor (1) passed similar tests at STC and LTC (8 threads), while a very large one (2) passed STC quickly but failed LTC (8 threads). For the single-threaded case there is no functional change. Closes https://github.com/official-stockfish/Stockfish/pull/2337 Bench: 4088701 Fixup: remove redundant code.
