3f9f1eeefa [maglev] Depend on stable protos up to validity cell
Inline DependOnStablePrototypeChain to iterate only those maps which
share a validity cell with the receiver map. This resolves an issue
where maps after the holder object violate the stability invariants, but
doesn't require looking up what the actual holder is.
