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.
