I think there's some desire to keep all HeapObjects in objects.h (and to keep
the comment at the top of objects.h updated).

That also means you'd want to add heap verification support and maybe printing
support.

This class should get a comment explaining its layout too (probably similar to
the one that's in the serialization code right now).

I moved ModuleInfo into objects.h and removed scopeinfo.h again.  I'm keeping it
simple for now by not doing providing its own printing and verification
functions. But as ModuleInfo becomes more complex I will add these.

Can you at least provide a short comment on ModuleInfo?
