new functions are compatible before upgrading a function call to an intrinsic call. Sometimes users insert calls to ARC runtime functions that are not compatible with the corresponding intrinsic functions (for example, 'i8* @objc_storeStrong' instead of 'void @objc_storeStrong'). Don't upgrade those calls. rdar://problem/56447127
