  Changed paths:

    M llvm/lib/Passes/PassBuilder.cpp

  Log Message:
  -----------
  Reland "[CodeGen] Support start/stop in CodeGenPassBuilder (#70912)" (#78570)

Unfortunately the legacy pass system can't recognize `no-op-module` and
`no-op-function` so it causes test failure in `CodeGenTests`. Add a
workaround in function `PassInfo *getPassInfo(StringRef PassName)`,
`TargetPassConfig.cpp`.
