Original commit message:

    [heap] Make CompactTransitionArray deserializer friendly

    Add a pre-loop over transition arrays during compaction, that checks
    whether compaction is needed at all, and whether any of the entries are
    still uninitialized values as part of deserialization (and therefore no
    other targets can be dead). Bails out of compaction early if this is the
    case.
