This is how we originally controlled whether or not we printed out ownership annotations when we printed SIL. Since then, I have changed (a few months ago I believe) the ownership model eliminator to know how to eliminate these annotations from the SIL itself. So this hack can be removed. As an additional benefit, this will let me rename -enable-sil-ownership to -enable-sil-ownership-verifier. This will I hope eliminate confusion around this option in the short term while I am preparing to work on semantic sil again. rdar://42509812
