Addressed @ABataev remarks, investigated regression with PHI nodes in PR39774.ll and I have not spotted any other case involving PHI nodes, but I have several other cases and it happens quite rarely. I am not sure how-to generalize them and I think VPLAN might be helpful. Overall, I think it is ready.
