Just please make sure that whatever variant we end up deciding upon, the 
interface must become more like llvm's DWARF* classes, even if that means 
changing the llvm hierarchy to become more like LLDB's if need be. The end goal 
should be to make LLVM's DWARF classes good enough to be used in LLDB so we 
don't need to maintain two implementations.
