Before this change each built-in iterator object has a boolean `m_next_method_was_redefined`. If user code later changed the iterator’s prototype (e.g. `Object.setPrototypeOf()`), we still believed the built-in fast-path was safe and skipped the user supplied override, producing wrong results. With this change `BuiltinIterator::as_builtin_iterator_if_next_is_not_redefined()` looks up the current `next` property and verifies that it is still the built-in native function.
