I'm not familiar with the Clang codebase at all, so if someone could
point me to the parts of the code that would be a starting point to
build a control-flow graph then that be a great benefit.

If anyone has any ideas for on implementation for such a feature I would
also be keen to hear them.

Cheers, Brendan.
