        * rs6000.c (rs6000_expand_unop_builtin): Check icode not
        CODE_FOR_nothing.  Change switch to if.
        (rs6000_expand_binop_builtin): Same.
        (rs6000_expand_builtin): Expand builtin if target support enabled.
        (rs6000_init_builtins): Init builtin if target support enabled.
        (rs6000_common_init_builtins): Check icode not CODE_FOR_nothing.
