Can we move the pointer to the fixed array into the roots array (i.e. into
STRONG_ROOT_LIST) instead of explicitly visiting it? We wouldn't need to
explicitly visit it here, it is directly bound to the heap. 

We can keep the other non-heap data (e.g. the FP-mapping list) inside the
MaterializedObjectStore.

Done.
