Relax constrain in prevents_threat() When testing if a move blocks the threat path there is no reason to require the threat to be a slider. Indeed threat can be a double pawn push like in this example: r1bq1rk1/ppp1np1p/4n1p1/3p4/3P2Q1/2P1B3/PPBN2PP/R4RK1 w - - 0 16 Where white's move Rf6 blocks the threat f5. As a nice side effect we can retire the now useless helper piece_is_slider(). This patch kicks in only very rare cases, indeed the bench is still the same! bench: 5809010
