That's pretty complex. 2 initial thoughts:
1. Maybe add a generic getUseLoc or similar to abstract the implicit/non-implicit use locs.
2. Add tests for CXXDeleteExpr? I found that you have some logic for that in report functions but I did not see any tests.
Also I am starting to get a little concerned about our `issuePendingWarnings` method because it's getting much bigger, maybe we can split it up somehow (like reportGlobal, reportUAS, etc).
