[patch][commit] Collection of profiling information

Hi,

I've committed the attached patch which adds a missing bit of code 
generation needed for implementing pipeline models. It is similar to 
code already committed elsewhere for this purpose and was taken from the 
sim generator. Tested on an internal port which exposed the problem.
