The previous implementation of time tracing in NewPassManager is direct but messive.
The key codes are like the demo below:
```
/// Runs the function pass across every function in the module.
PreservedAnalyses run(LazyCallGraph::SCC &C, CGSCCAnalysisManager &AM,
LazyCallGraph &CG, CGSCCUpdateResult &UR) {
/// ...
PreservedAnalyses PassPA;
{
TimeTraceScope TimeScope(Pass.name());
PassPA = Pass.run(F, FAM);
}
/// ...
}
```
It can be bothered to judge where should we add the tracing codes by hands.
With the PassInstrumentation framework, we can easily add `Before/After` callback
functions to add time tracing codes.
