We should think about the invariants for the MarkedBlock's BlockState.

To be more specific, blocks whose marks aren't cleared during an EdenCollection could potentially still be in the Allocated block state. Historically the invariant has been that all blocks after a collection are in the MarkedState. It might be the case that we can relax this invariant for EdenCollections.

This issue can be easily reproduced by applying the patch at <https://webkit.org/b/129067>, and running testapi on a 64-bit debug build.
