Fully support make-style `.d` dependencies file output by making following improvements: * All correct dependency file render when cache hit for a different output file location. The dependency file should list the correct output path, not the stale output path for the initial compilation * When enable a path prefix mapper to canonicalize the path, the dependency file should render the input file correctly as the input file path on disk. rdar://132250067
