1. OCMock: Fix crash when running on iOS 15 device. …

   `object_getClass` crashes on some arguments when being run on an iOS 15
   device. `object_getClass` is needed because OCMock needs to detect if
   the argument is actually a `OCMPassByRefSetter`, which disguises as a
   pointer to an object (`id *`) but is actually an object (`id`).
   The solution is to make sure before calling `object_getClass` that the
   type encoding of the argument is actually a pointer to an object, and
   then it should be safe to call `object_getClass`.
   The problem is that the value was previously wrapped with an `NSValue`,
   which disguised the type encoding as a `void *`. Therefore the check of
   whether the argument is `id *` is done before it will be wrapped with
   `NSValue`.
