CodeGeneratorBug.cpp:

Browse Source 
* Temporarily externing InputArgv to print it out for the benefit of LLI command
  needed to reproduce the result.
* Print out the list of functions currently being tested
* ListReducer now returns a bool if there was a failure, so test for it

ListReducer.h:
* Handle the case where there is no problem by returning true if failure is
  found. Also correctly handles the case when there is only 1 pass/function.

Miscompilation.cpp:
* ListReducer now returns a bool if there was a failure, so test for it
