This is somewhat working version able to handle cross block DSE across PHI merges. This is not a final patch in any means. It should be possible to extract several NFCs, split to smaller pieces, tests, etc. If someone wants to take over and continue it would be great. If not I will do my best to push changes as schedule permits. Anyway any feedback is welcome.
