  -----------
  [NewPM] Only verify loop for nonskipped user loop pass

No verification for pass mangers since it is not needed.
No verification for skipped loop pass since the asserted condition is not used.

Add a BeforeNonSkippedPass callback for this. The callback needs more
inputs than its parameters to work so the callback is added on-the-fly.

  Log Message:
  -----------
  [NewPM][CodeGen] Introduce machine pass and machine pass manager

machine pass could define four methods:
- `PreservedAnalyses run(MachineFunction &, MachineFunctionAnalysisManager &)`
- `Error doInitialization(Module &, MachineFunctionAnalysisManager &)`
- `Error doFinalization(Module &, MachineFunctionAnalysisManager &)`
- `Error run(Module &, MachineFunctionAnalysisManager &)`

machine pass manger:
- MachineFunctionAnalysisManager:
  Basically an AnalysisManager<MachineFunction> augmented with the ability to
  register and query IR analyses
- MachineFunctionPassManager: support only two methods, `addPass` and `run`
