[cfe-dev] How to assign a Custom Diagnostic IDs in Clang Tool

[Roman Popov via cfe-dev]

Looks like DiagnosticEngine does not allow to be instantiated with
User-supplied IDs.
The problem is that DiagnosticIDs is not an interface to IDs database, but
rather a final class not designed for inheritance.

So I don't find a way how Clang diagnostic library can be reused by 3rd
party tool.
