[PATCH] D17442: [LPM] Remove the last worrisome split in the primary loop pass pipeline, allowing LICM and friends to always run over the outer loop after unrolling has a chance to remove the inner loop.

Hm, when I tried something like this I got a number of failures/huge regressions because LoopSimplifyCFG currently is much weaker than SimplifyCFG, so all later passes were basically crippled. Have you seen any of these?
