Alias manager does not know whether generator parameters are passed by reference. This didn't matter, because every generator had at least one function call (hphp_continuation_done()) that pretty much disabled unused variable elimination. This diff fixes that, lets us get rid of artificial function calls in generators and will allow later improvements in alias manager.
