The requirement for the definition is use of isa/dyn_cast or calling functions of pointer-packed data types such as DenseMap or PointerIntPair. Add missing includes to these headers.

2019-01-10[analyzer] pr38838, pr39976: Fix crash on diagnosing before implicit destructor.Artem Dergachev
We need to be able to emit the diagnostic at PreImplicitCall, and the patch implements this functionality. However, for now the need for emitting such diagnostics is not all that great: it is only necessary to not crash when emitting a false positive due to an unrelated issue of having dead symbol collection not working properly. Coming up with a non-false-positive test seems impossible with the current set of checkers, though it is likely to be needed for good things as well in the future.
