Todd Gamblin e4b898f7c3 lazy_lexicographic_ordering: Add short-circuiting with _cmp_fast_eq ... Add a `_cmp_fast_eq` method to the `lazy_lexicographic_ordering` protocol so that implementors can short-circuit full comparison if they know (e.g. with a hash) that objects are equal (or not). `_cmp_fast_eq` can return True (known true), False (known false), or None (unknown -- do full comparison).
