  Changed paths:
    M llvm/include/llvm/IR/PrintPasses.h
    M llvm/lib/CodeGen/MachineFunctionPass.cpp
    M llvm/lib/IR/PrintPasses.cpp
    M llvm/lib/Passes/StandardInstrumentations.cpp
    A llvm/test/Other/print-changed-machine.ll

  Log Message:
  -----------
  [MachineFunctionPass] Support -print-changed and -print-changed=quiet

-print-changed for new pass manager is handy beside -print-after-all.
Port it to MachineFunctionPass.

Note: lib/Passes/StandardInstrumentations.cpp implements a number of
misc features. If we want to use them for codegen, we may need to lift
some functionality to LLVMIR.
