Fixes SI-6259. Unable to use typeOf in super call of top-level object.

This works around the issue of the inability to use classOf for top-level object classes by inventing a new
anonymous class and instantiating it just to grab its class.  Since the class is a nested type of the
top-level object it'll be in the same classloader unless some kind of evil behavior is afoot.

This patch should be undone if ever SI-2453 ever gets fixed, or we wind up with a direct way to grab
the class of an object.
