Original change's description:
> [wasm] Maintain link from Instance to Module.
>
> This moves the link from a {WasmInstanceObject} to its corresponding
> {WasmModuleObject} into the right place and also makes it strong. This
> ensures that an instance always keeps the underlying module alive and
> hence removes the situation of an "orphaned instance".
