    Return non-legacy ranges in range.h.
    
    int_range<1> is a legacy range (think anti ranges, legacy VRP, etc).
    There is a penalty for converting anything built with <1> to
    non-legacy.  Since most of the uses of these functions are now ranger,
    we can save a miniscule amount of time by converting them to
    non-legacy.
    
    gcc/ChangeLog:
    
            * range.h (range_true): Return int_range<2>.
            (range_false): Same.
            (range_true_and_false): Same.
