Original change's description:
> [runtime][gc] Drop AllocationSite::weak_next field for sub-literals
>
> Use AllocationSite without Weaknext field for all the allocations in nested
> literal except for Root. The nested field is sufficient to link all the
> allocations in a nested literal. Only the Root is added to heap weak_alloc_list
> for GC to traverse
>
