>       * gimple-match.h (struct gimple_match_op): Add reverse field.

Jonathan privately remarked that the new member should probably be initialized 
in the constructors (thanks!).  Done thusly, applied on mainline as obvious.

        PR tree-optimization/86659
        * gimple-match.h (gimple_match_op constructors): Initialize reverse.
