Updated this to address Anna's comments.

- I've made the state smaller. It is just now a set of SymbolRefs for methods instances that have been dealloc'd.
- I've hoisted isSuperDeallocMessage() to early return when possible.
- I've added tests with -analyzer-output=text.
- I've moved the lazy initialization of the dealloc selector identifier to isSuperDeallocMessage()
