I'm not very familiar with the old pass manager infrastructure (I got involved only in new pass manager'y stuffs) and I don't want to cause troubles.
To double check, I just need to remove the `addRequired()` call/INITIALIZE_DEPENDENCY from the pass right? If so, I'll do another round of testing then commit.
