No. The type predictions come in via Node::getHeapPrediction() for those nodes that were generated from bytecodes that had value profiles. The bytecode parser sets the heap prediction (see OpInfo() arguments to addToGraph()) and the prediction propagator propagates those heap predictions to the normal predictions.
