It is pretty easy to link in a project pass into opt.  You will need
to replicate LinkAllPasses for your pass and fiddle with makefile for
opt.  See below for an example of most of the work you would need to
do.  Note that this only matters if you want to work in a project for
your new pass rather than just working in the tree.
