Derrick Stolee 4c7bb45269 test-reach: test get_reachable_subset ...

The get_reachable_subset() method returns the list of commits in
the 'to' array that are reachable from at least one commit in the
'from' array. Add tests that check this method works in a few
cases:

1. All commits in the 'to' list are reachable. This exercises the
   early-termination condition.

2. Some commits in the 'to' list are reachable. This exercises the
   loop-termination condition.

3. No commits in the 'to' list are reachable. This exercises the
   NULL return condition.
