Summary:

In a non-arc project, specifying -fobj-arc against a particular file to compile with ARC still triggers analyser warnings inside Xcode.

Steps to Reproduce:

1. Create a new single-view iOS project, ensure ARC is switched *off* for the project.
2. In Build Phases, add -fobj-arc to the generated ViewController class. [DOH.  TRY OBJC-ARC, IDIOT]
3. add the following code to the ViewControllers viewDidLoad

    NSString* leak = [[NSString alloc] initWithString:@"I will be reported as a leak despite -fobj-arc"];
    NSLog(@"LEAK: %@", leak);

4. Add the following code to the AppDelegates application:didFinishLaunchingWithOptions:

    NSString* leak = [[NSString alloc] initWithString:@"I *SHOULD* be reported as a leak as this is a non-ARC project"];
    NSLog(@"LEAK: %@", leak);

5. Select Product->Analyse

Expected Results:

The leak in AppDelegate should be reported as the file (and indeed the project) are not ARC-enabled.  The leak in the ViewController should *not* be reported as it's ARC compiled.

Actual Results:

Both leaks are reported.
