actually is it possible to add this into `EarlyFPM` below? it's nice to have fewer module->function adaptors. (e.g. in `EarlyFPM` we run all the function passes on a single function before moving to the next one which is nice for memory locality)

sorry for suggesting this so late, since it'll require updating all the pipeline tests... but first check that none of the other tests fail
