leonardchan added a comment.

- Added tests for checking that `noderef` can only be used for C style pointers and arrays (not usable for references or ObjC pointers)
- Added warnings for dereferencing a noderef expression where we cannot trace back the original declrefexpr.
- Added warning for adding `noderef` on a type that `noderef` cannot be attatched to.
- Added warning group.
- Use SmallPtrSet instead of std::unordered_set
