This is a quick fix for the recent bailout-on-uninitialized feature of
the serializer, which does not work with resumables. For now, simply
treat the ResumeGenerator bytecode as if it was an exception handler
entry point. I want to revisit this later because the proper fix might
be to teach the serializer about the SwitchOnGeneratorState bytecode.
