    Ojective-C, Darwin : Adjust category superclass ref names (NFC).
    
    Make the order of the class and superclass match the metadata
    order from clang.  Makes it easier to compare produced meta-
    data between implementations.
    
    gcc/objc/ChangeLog:
    
            * objc-next-runtime-abi-02.c
            (next_runtime_abi_02_category_decl): Adjust category
            superclass name ordering.
