Make possible to don't track cache dependencies.

Make possible to don't track cache dependencies.

If 'trackCacheDependencies' is set to 'false', this makes DDC
compilation of Angular2 project about 10% faster.

Unfortunately I was not able to avoid creating ResultDescriptor(s) and
adding them into WorkItem.inputTargetedResults altogether. It is used
in AnalysisTask._findCyclicPath() to create InfiniteTaskLoopException
with additional information.

"batch mode" has a special meaning for dartanalyzer :-( Perhaps "batch mode, so"
--> "such a way"
