Just regular merge conflicts when we merge this into the Swift fork. This PR is upstreaming ptrauth support and started off based on the downstream code, but after a few iterations of review it looks a bit different. That's totally fine, as the result is better for it, but git will need a hand with the merge. The only reason I'm bringing it up is because last time this PR landed on a Friday afternoon (before it got revert) which left us little to deal with all this.
