[PATCH] D17528: [analyzer] Warn on use of 'self' after call to to [super dealloc].

Referring to 'self' after  a call to [super dealloc] is a use-after-free in Objective-C because NSObject's -dealloc frees the memory pointed to by self. This patch extends the ObjCSuperDeallocChecker to catch this error.
