    aix: Move AIX math builtins before new builtin machinery.
    
    The new builtin machinery has an early exit, so move the AIX-specific
    builtins before the new machinery.
    
    gcc/ChangeLog:
    
            * config/rs6000/rs6000-call.c (rs6000_init_builtins): Move
            AIX math builtin initialization before new_builtins_are_live.
