I'd like someone more active on the Clang side to comment about this, but here is my 2 cents...

It seems like it'd be nice to not populate or run or otherwise build up the legacy pass managers when using this option. I guess I would expect something to more split early between the two pipelines, and then merge back before doing codegen.

I'm also somewhat hesitant with the '-middle-end-...' naming, but not sure what would work better. We don't have anything even comparable with the legacy PM, so maybe just "-llvm-custom-passes" or something similar?
