Harvesting maps from the stub cache for megamorphic ICs is both slow (linear in the size of the stub cache) and imprecise (as it finds all maps that have a cached handler for the given property name). In the canonical megamorphic situation, this type feedback is useless anyway. The interesting case is when we can filter it down to a single map; however in these cases it is often possible to derive this map just by looking at the HGraph, which is both faster and more reliable.
