Allow users to run a dependency scan with a cc1 command line in addition to a driver command line. The scan was being carried out with a cc1 command line, but `DependencyScanningWorker::computeDependencies` assumed that the user always provided a driver command line. Now `DependencyScanningWorker::computeDependencies` can handle the case where the user provides a cc1 command line.
