Make code nice
Created attachment 39368 [details] Patch v1
Please make the StructureTransitionTable() constructor call setSingleTransition(0), instead of handling the bitfield manually. Too bad we can't use PtrAndFlags here! We need a trick to help the leaks tool 'see' m_singleTransition. How about refactoring PtrAndFlags into a base class that has no constructor, and is safe to use in a union? r=me if you do those two things.
