Yeah, I am kind of new to these tree optimizers, so I thought there 
might be some sort of official way to know these things.

For development and testing, I will just always run the pass.  It might 
get some hits in C++ cni code, but it is exceedingly unlikely that it is 
at all useful for c, ada, fortran, etc.
