        * fold-const.c (fold_binary): Use op0 and op1 instead of arg0
        and arg1 for optimizations of comparison against min/max values.
        Fold arg0 to arg1's type for optimizations of comparison against
        min+1 and max-1 values.

        * gcc.c-torture/compile/20070419-1.c: New test.
