@Michael137 Could you clarify a bit, what is the correct place for such a unit test? As for `ASTContext` methods similar to newly proposed `getPointerAuthType` (like `getQualifiedType` and `getCVRQualifiedType`), I've not found unit tests with them. As for `Qualifiers` class also touched in this PR, I've not found tests for it at all. Newly proposed `PointerAuthQualifier` qualifier, obviously, also has no unit tests now, but if we want to implement them, they should be placed somewhere near unit tests for `Qualifiers` which are absent as well.
