Summary: This patch converts the InstructionTables class into a subclass of mca::Stage. This change allows us to use the Stage's inherited Listeners for event notifications. This also allows us to create a simple pipeline for viewing the InstructionTables report. I have been working on a follow on patch that should cleanup addView in InstructionTables. Right now, addView adds the view to both the Listener list and Views list. The follow-on patch addresses the fact that we don't really need two lists in this case. That change is not specific to just InstructionTables, so it will be a separate patch.
