Don't add a tail keyword to calls to ObjC runtime functions if the calls are annotated with notail. r356705 annotated calls to objc_retainAutoreleasedReturnValue with notail on x86-64. This commit teaches ARC optimizer to check the notail marker on the call before turning it into a tail call. rdar://problem/38675807 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@356707 91177308-0d34-0410-b5e6-96231b3b80d8
