Changes pertaining to supporting instrumentation:
* Constructors for easier construction thereof, and also of
argument vectors for both clean and dirty helpers.
* Allow/require instrumenters to supply helper-lookup functions.
* Clarify situation re whether or not dirty helpers get passed
a pointer to the guest state.
* Sanity check IR after instrumentation.
Myriad other changes to make this all work.
