I spent some time on this a while back and can't remember seeing MSVC emitting these records, but I might have missed something. Good that you figured it out!

As far as I know, neither Visual Studio nor WinDbg use these symbols. My motivation for adding these is for an internal tool at Microsoft that performs binary analysis that requires these symbols to exist.

Added a `visitKnownRecord`.
