As of r255720, the loop pass manager will DTRT when passes update the loop info for removed loops, so they no longer need to reach into LPPassManager APIs to do this kind of transformation. This change very nearly removes the need for the LPPassManager to even be passed into loop passes - the only remaining pass that uses the LPM argument is LoopUnswitch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@255797 91177308-0d34-0410-b5e6-96231b3b80d8
