Setting a view's layer contents to nil causes subview layers to be dealloc'd rdar://15811803

| Summary: | |
| When a view is removed from it's superview and subsequently dealloc'd, if it sets it's layer.contents = nil this will cause all subview layers to be dealloc'd even though those subviews retain a pointer to their layer. Any attempt to send messages to those subviews that references the view's layer (now a zombie) will crash the app. | |
| The attached example is of course contrived, however the real world problem caused by this is when using CATiledLayer which has async drawing. It is a requirement to set layer.contents to nil in the view dealloc in order to block until any remaining drawing blocks are completed.* | |
| *Yes I know that if dealloc is being called how can there still be active drawing blocks? Because of rdar://8640386 that's how | |
| Steps to Reproduce: | |
| 1. Add a view to the window (view1) | |
| 2. Add a subview (view2) to view1 and retain it |
