Interpreter cleanups:

Get rid of support for DebugMode (make it always off).
Mung some comments.
Get rid of interpreter's PROFILE_STRUCTURE_FIELDS and PerformExitStuff
 which have been disabled forever.
Get rid of -abort-on-exception (make it always on).
Get rid of user interaction stuff (debug mode innards).
Simplify Interpreter's callMainFunction().
