The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType.

- Change constructor and create methods to accept a CXXRecordDecl* (RecordDecl*)
instead of a ScopedDecl* for PrevDecl. This causes the type checking
to be more tight and doesn't break any code.
RecordDecl:
- Don't use the NextDeclarator field in ScopedDecl to represent the previous
declaration. This is a conflated use of the NextDeclarator field, which will
be removed anyway when DeclGroups are fully implemented.
- Instead, represent (a soon to be implemented) chain of RecordDecls using a
NextDecl field. The last RecordDecl in the chain is always the 'defining'
RecordDecl that owns the FieldDecls. The other RecordDecls in the chain
are forward declarations.
