Fix itself looks good to me, but why don't we add a proper
PrintOptimizeStringConcat debug block instead of the assert?

I think OptoStringConcat should fail gracefully on graph mismatch
anyway, not crash the fastdebug build. Is it possible to have anything
else besides Bool or Con as an input for If?

Thanks,
