[PATCH] [analysis] Add test for missing -dealloc method in classes with an ivar

[David Kilzer]

I would have added a similar test for a class with a @property, but I need to fix a couple of bugs before posting that patch.

Currently the checker doesn't warn at all for classes with no -dealloc method and a (retain) @property, and after fixing that issue, leaving out the @synthesize statement causes the checker to crash (apparently because it's trying to attach the warning to the @synthesize statement when it doesn't exist).
