compiler, runtime, testing, common: Centralize Execution/Evaluation

Browse Source 
Centralize the execution of statements and evaluation of expressions
so that the user can specify a debugging "callback" after every
execution/evaluation.

The callback can be used for myriad things, but it seems likely that
it will be useful for implementing:
1. Testing
2. Debugger
