Instead of loop across all legal moves to find a mate loop across possible check moves only. This reduces more then 10 times the number of moves to check for a possible mate. Also rename generate_checks() in generate_non_capture_checks() so to better clarify what the function does. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
