I think it'd be fine to pass ASTContext to the DiagnosticConsumers. It would be
useful to find out exactly what extra information the mangled names have that
we do not want to see in the issue_hash.
One issue that I see with the current approach is that we do not differentiate
methods from different classes/namespaces. Is this by design?

Sounds good to me. I agree that this is out of scope for this patch.

We should use the new hash here.
