Extend stack to ss-5, and remove conditions The `&& (ss-1)->killers[0] ` conditions are there seemingly to protect accessing ss-5. This is unneeded and not so intuitive (as the killer is checked for equality with currentMove, and that one is non-zero once we're high enough in the stack, this protects access to ss-5). We can just extend the stack from ss-4 to ss-5, so we can call update_continuation_histories(ss-1, ..) always in search. This goes a bit further than #1881 and addresses a comment in #1878. passed STC: http://tests.stockfishchess.org/tests/view/5c1aa8d50ebc5902ba127ad0 LLR: 3.12 (-2.94,2.94) [-3.00,1.00] Total: 53515 W: 11734 L: 11666 D: 30115 passed LTC: http://tests.stockfishchess.org/tests/view/5c1b272c0ebc5902ba12858d LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 140176 W: 23123 L: 23192 D: 93861 Bench: 3451321
