[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`
