Sorry for the delayed replies, I was busy with the LLVM dev conference/travel.

Yes it looks good to me. All the issues I know of have been resolved and any refinements can be done later. I think some downstream users have already been using this pass (judging from the occasional bug/perf issue reports), wider usage after default enablement might uncover more opportunities.
