/* Used to verify that the JIT resolves the ObjectIsTypedObject tests
 * used in the TO.objectType() method, among other places.
 *
 * In this case the argument type is always a TypedObject (though not
 * a unique one), so ObjectIsTypedObject resolves to true and there
 * should be no exceptions.
 *
 * Load this into the js shell with IONFLAGS=logs, then exit and run
 * iongraph.  You're looking for a smallish function within the
 * "self-hosted" domain.  Look for a call to ObjectIsTypedObject far
 * down in the graph for pass00, with a subgraph before it that looks
 * like it's comparing something to a string and to null (this is the
 * inlining of IsObject).  (All of this is at the mercy of the way the
 * code is currently written.)
