Why isn't PostStmt<DeclStmt> invoked? with code to reproduce.

I’m trying to understand why this checker behaves as it does. I have a project where I would like to register for PostStmt, but, in spite of the fact that this is one of the callbacks mentioned explicitly in CheckerDocumentation.cpp, it doesn’t ever get invoked.

I just synced my LLVM and Clang trees last night.

Thanks much!
