Remove Identity nodes if num_inputs * num_outputs <= num_inputs + num_outputs. Exceptions are Identity nodes after Variable nodes, and Identity nodes after Switch nodes when removing the node would require anchoring a control dependency on the Switch.
Another exception is Identity nodes where inputs or outputs cross a device boundary, since we are not allowed to remove Identity nodes after _Recv that might be inserted in the graph later.
