    Original commit message:
    The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include:
    
    * Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions.
    * The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization.
    
    Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.
