[PATCH] middle-end/108209 - typo in genmatch.cc:commutative_op

[Richard Biener via Gcc-patches]

The early out for user-id handling indicated commutative
rather than not commutative.

Bootstrapped and tested on x86_64-unkown-linux-gnu, pushed.

        PR middle-end/108209
        * genmatch.cc (commutative_op): Fix return value for
        user-id with non-commutative first replacement.
