I had a similar question and Chris recommended that I edit the 
addPassesToEmitAssembly method. Quoting him:

" Basically, if you want to work on the code generator, this is what you
should do:  Add your pass to the addPassesToEmitAssembly method for the
target of your choice, and in your pass implement the getPassName() 
method to provide a nice user-friendly name. "

You can explicitly specify where (w.r.t other passes) your pass will 
execute in the addPassesToEmitAssembly method.
