In a few days ago we will propose a new PR for a different implementation for integrated DTLTO, but without the use of "DTLTO backend". That's why we call it internally "no-backend DTLTO".

By "DTLTO backend" do you mean the new CGThinBackend class? Since that's a big part of the LLVM piece, I've kind of held off on reviewing for now since I'd like to compare the 2 approaches first and I'm not sure how much is changing.
