    Improve mark-compact object grouping interface. · 6297a191
    deanm@chromium.org authored
    The main goal was to improve O(n^2) behavior when there are many object groups.  The old API required the grouping to be done on the v8 side, along with a linear search.  The new interface requires the caller to do the grouping, passing V8 entire groups at a time.  This removes the group id concept on the v8 side.
    
      - Changed AddObjectToGroup to AddObjectGroup.
      - Removed the group id concept from the V8 side.
      - Remove a static constructor while I'm here, lazily initialize
        the object groups list.
      - Cleaned up return by non-const references to return pointers.
