Introduce the core infrastructure needed to model a complete
redeclaration chain for Objective-C classes, including:
- Using the first declaration as the canonical declaration.
- Using the definition as the primary DeclContext
- Making sure that all declarations have a pointer to the definition
data, and the definition knows that it is the definition.
- Serialization support for when a definition gets added to a
declaration that comes from an AST file.
However, note that we're not taking advantage of much of this code
yet, because we're still re-using ObjCInterfaceDecls.
