shouldn't do AU.setPreservesCFG(), because even though CodeGen passes don't modify the LLVM IR CFG, they may modify the MachineFunction CFG, and passes like MachineLoop are registered with isCFGOnly set to true. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77691 91177308-0d34-0410-b5e6-96231b3b80d8
