    middle-end/108209 - typo in genmatch.cc:commutative_op
    
    The early out for user-id handling indicated commutative
    rather than not commutative.
    
            PR middle-end/108209
            * genmatch.cc (commutative_op): Fix return value for
            user-id with non-commutative first replacement.
