cue: implement unary comparators and remove ranges

This introduces a new unification type that accumulates
overallapping values that cannot be represented as a single
value. Before ranges would simplify as they were unified.
This unification type is a generalization of this mechanism.

As a result of this change, interval arithmetic is gone
(was not allowed according to the spec.)

Fixes cuelang/cue#11.
