Max Kazantsev ce2d739dc1 [LoopSimplifyCFG] Pay respect to LCSSA when removing dead blocks ...

Utility function that we use for blocks deletion always unconditionally removes
one-input Phis. In LoopSimplifyCFG, it can lead to breach of LCSSA form.
This patch alters this function to keep them if needed.
