    Revert of Reland of Remove slots that point to unboxed doubles from the StoreBuffer/SlotsBuffer. (patchset #3 id:40001 of https://codereview.chromium.org/988363002/)
    
    Reason for revert:
    Increased rate of Chrome crashes. Requires further investigation.
    
    Original issue's description:
    > Reland of Remove slots that point to unboxed doubles from the StoreBuffer/SlotsBuffer.
    >
    > The problem is that tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field).
    > This CL also adds useful machinery that helps triggering incremental write barriers.
