Summary:
This models ARC implementation of dealloc, see https://clang.llvm.org/docs/AutomaticReferenceCounting.html#dealloc. Dealloc methods can be added to ObjC classes to free C memory for example, but the deallocation of the ObjC instance variables of the object is done automatically. So here we add this explicitly to Infer:
1. First, we add an empty dealloc method when it is not written explicitly.
2. For each dealloc method (including the implicitly added ones) we add calls to dealloc of the ObjC instance variables.
