[PATCH] D141487: [LoopUnroll] Directly update DT instead of DTU.

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

this causes `opt -passes=loop-unroll-full` to crash on

  define void @foo() {
  bb:
    br label %bb1
      
  bb1:                                              ; preds = %bb1, %bb1, %bb
    switch i1 true, label %bb1 [
      i1 true, label %bb2
      i1 false, label %bb1
    ]
      
   bb2:                                              ; preds = %bb1
    ret void
  }

so I've reverted this for now
