Summary: This is a tweak to r368311 and r368646 which auto upgrades the calls to objc runtime functions to objc runtime intrinsics, in order to make sure that the auto upgrader does not trigger with up-to-date bitcode. It is possible for bitcode that is up-to-date to contain direct calls to objc runtime function and those are not inserted by compiler as part of ARC and they should not be upgraded. Now auto upgrader only triggers as when the old style of ARC marker is used so it is guaranteed that it won't trigger on update-to-date bitcode. This also means it won't do this upgrade for bitcode from llvm-8 and llvm-9, which preserves the behavior of those releases. Ideally they should be upgraded as well but it is more important to make sure AutoUpgrader will not trigger on up-to-date bitcode.
