    [compiler] Make AllocationSite never-serialized · 9a23caf0
    Georg Neis authored
    To get there, also:
    
    - Refactor AllocationSite serialization as necessary.
    
    - Make some accessors on AllocationSite atomic.
    
    - Add JSObjectRef::raw_properties_or_hash().
    
    - Eliminate use of IsFastLiteral in JSCallReducer. It isn't really
      needed there and we want to have only a single piece of code
      traversing boilerplates. (We still have a separate traversal in the
      serializer but that will be removed soon.)
    
    - Merge IsFastLiteral checks into JSCreateLowering's
      TryAllocateFastLiteral.
      Note: TryAllocateFastLiteral doesn't explicitly look at the
      boilerplate's elements kind beyond bailing out for
      DICTIONARY_ELEMENTS in the beginning. After that it looks only at
      the backing store instance type. There is no room for confusion
      because, while elements kind transitions can generally happen
      concurrently to TryAllocateFastLiteral, boilerplates can never
      transition to DICTIONARY_ELEMENTS (added a CHECK for that).
    
    - Slightly adapt CompilationDependencies and remove obsolete comments.
    
    - Fix JSHeapBroker::ClearReconstructibleData (clearing of Refs in
      stress mode) to exclude JSObjectRefs with extra data.
