Maybe I'm misunderstanding this CL.  Are we spending a bit in RenderObject
purely for debug information?  Generally speaking, that's a poor tradeoff.  Bits
in RenderObject are very valuable.

         ADD_BOOLEAN_BITFIELD(layoutDidGetCalled, LayoutDidGetCalled);
 
         ADD_BOOLEAN_BITFIELD(hasPendingResourceUpdate, HasPendingResourceUpdate);
 
         // from RenderBlock
         ADD_BOOLEAN_BITFIELD(childrenInline, ChildrenInline);
         ADD_BOOLEAN_BITFIELD(hasColumns, HasColumns);
