> Debugger fetches the return value of a function when we break at return.

> passed to the runtime function and is then stored in thread local data.

> Also changes full-codegen implementation to match that of ignition.
> The return value from full-codegen is also stored in thread local data.
> The return value is fetched directly thread local data instead of
> finding it by iterating over frames.
