Issue Description:

From the Class Metadata section of the ABI Stability manifesto:

"Library evolution may present many changes to what exactly is present and will likely make many of the contents opaque to accommodate changes."

We need to decide what the class metadata should contain and what should be opaque as part of locking down the ABI.

I think this is done. We've essentially made everything opaque except for the generic parameter area.
