Limit has_game_cycle() to only upcoming repetition use the original algorithm according to the paper http://web.archive.org/web/20201107002606/https://marcelk.net/2013-04-06/paper/upcoming-rep-v2.pdf, which detects accurately if a position has an upcoming repetition. The 'no progress' part of has_game_cycle has been removed, the function has been renamed to upcoming_repetition to reflect this. As a result of this fix, to the best of our knowledge, all PVs for completed iterations that yield a mate or decisive table base score now end in mate or contain a TB position, respectively. passed non-regression STC: https://tests.stockfishchess.org/tests/view/6679fa1d0c2db3fa2dcecbf2 LLR: 2.96 (-2.94,2.94) <-1.75,0.25> Total: 63584 W: 16666 L: 16472 D: 30446 Ptnml(0-2): 186, 7552, 16146, 7698, 210 Passed non-regression LTC: https://tests.stockfishchess.org/tests/view/667ac965e439ed1c7a9ca042 LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 464574 W: 117493 L: 117729 D: 229352 Ptnml(0-2): 311, 52468, 126974, 52214, 320 closes https://github.com/official-stockfish/Stockfish/pull/5432 bench: 1209805
