[llvm-dev] Moving to ORCv2 - Compiling debuggable code?

[River Riddle via llvm-dev]

If you are creating your own object linking layer via LLJITBuilder, you
could add the notification yourself. For RTDyldObjectLinkingLayer, you can
use `setNotifyLoaded`. For ObjectLinkingLayer, I think you would need to
use a `ObjectLinkingLayer::Plugin`. I was able to hook the existing GDB
registration listener this way.
