832272da71 8178349: Cache builtin class loader constraints to avoid re-initializing itable/vtable for shared classes
Record loader constraints for built-in class which is loaded by app loader or platform loader in shared archive in dump time.  When the class loaded from shared archive at runtime, directly check loader constraints using the saved info so avoid lengthy relayout i/v-table at class link stage.
