Arthur Eubanks 34a8a437bf [NewPM] Hide pass manager debug logging behind -debug-pass-manager-verbose 
Printing pass manager invocations is fairly verbose and not super
useful.

This allows us to remove DebugLogging from pass managers and PassBuilder
since all logging (aside from analysis managers) goes through
instrumentation now.

This has the downside of never being able to print the top level pass
manager via instrumentation, but that seems like a minor downside.

Yuanfang Chen f5b5ccf2a6 Reland "Revert "[NewPM][CodeGen] Introduce machine pass and machine pass manager"" 
This relands commit 320eab2d55.

The test failed because it was looking for x86-linux target
unconditionally. Now it gets the default target.

Yuanfang Chen 911565d108 [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`
