It is indeed possible. I have a simple example of doing this for the "hello
pass" in [1] in the "helloPass" folder. In the same directory it also shows
how to load the pass as a clang plug-in and have it run automatically. This
built fine against LLVM3.5 but I've not tested if this builds against trunk.
