In Objective-C, it's common for some frameworks to mark some methods like `init` as unavailable in the `@interface` to prohibit their usage.
However, these frameworks then often implemented said method and refer to it in another method that acts as a factory for that object. The recent change to how messages to `self` are type checked in clang (r349841) introduced a regression which started to prohibit this pattern with an `X is unavailable` error. This patch addresses the aforementioned regression.
