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.
