Fix RefPtr's move assignment operator

Fix RefPtr's move assignment operator so that the moved RefPtr is always
null after the assignment. Because the previous implementation was not
swapping with a temporary variable, this wasn't necessary the case and
this behavior is unexpected.

Thanks to Mikhail Pozdnyakov for pointing this out.

DevTools: Roll Closure compiler to d8f30cda5f, enforce member access checks

This patch enforces the visibility checks for members annotated with
@private and @protected, as well as starting with a single underscore ('_'),
which means a private type member.
