1. Changed into a positive test with -ast-print
2. Just `QualType BaseType = ASE->getBase()->getType().getNonReferenceType();`
and dropped all the call for getNonReferenceType() in later checks.
Thank you for your time for the review! I do have one more question to ask. I
don't understand the log of the build failure, would you be able to give me a
bit of a hint?
