There was a program by Power Builder called Sleuth QA that would profile the functions in Delphi and C++ Builder applications. I'm certain there would be a way to output these functions in a usable format, plus allow you to determine some valuable stats about each. Unfortunatly Power Builder has gone under, but I believe they open-sourced all of their code and made their products available, I’m just not sure where. A little searching around might find this out though.
