@cachemeifyoucan As far as I can tell, it's already the case that for non-LTO 
builds, this pass is only added for optimization level > 0. Is that ok to do 
for all builds?

I checked and directly providing clang with IR that contains 
`llvm.objc.clang.arc.use` and compiling it with `-O0` fails instruction 
selection as a result of not running this pass, so I'm assuming these 
intrinsics are only introduced at `-O1` or higher.
