C++: Expose PresentIRFunction and override in cpp/count-ir-inconsistencies
...
The `toString` implementtion that `PresentIRFunction` uses may result in very

string size and still suffices when just counting the number of inconsistencies.

functions, as demonstrated by test.cpp, which now "fails" (i.e. works) for the new test
cases instroduced
in the previous commit.
