Add a first end-to-end test for action equality

This test also demonstrates the notion of equality used in our
action graph: actions are considered equal, if they are defined in
the same way (regardless of where they are defined); when looking up
actions in cache, however, the inputs are considered extensionally.
The test also verifies that if one dumps the action graph, the
origins of an action (as the same action can be defined in many
places) are reported correctly.
