/* Used to verify that the JIT resolves the ObjectIsTypedObject tests

*
* In this case the argument type is always a TypedObject, so

*
* 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
