[ADT] IntervalMap: fix setStart and setStop
Summary:
These functions currently require that the new closed interval has a length of
at least 2. They also currently permit empty half-open intervals. This patch
defines nonEmpty in each traits structure and uses it to correct the
implementations of setStart and setStop.
