Replying to myself again...

After sifting through many of the existing transforms, I discovered  
that new command-line parameters can be added to opt simply by  
declaring them in the transform code, such as in this example from  
Internalize.cpp:

   static cl::opt<std::string>
     APIFile("internalize-public-api-file", cl::value_desc("filename"),
       cl::desc("A file containing list of symbol names to preserve"));

So, the calling program can simply pass the name of a file to opt as a  
parameter, and it will then know exactly where the analyzer will send  
its output.
