Rather than copying the old incr comp dir and then modifying it. This saves a copy/hardlink for files that are modified. And it removes the need for accurate work product tracking to avoid accumulating cruft, which is non-trivial. We don't accurately track the pre-LTO bitcode files for ThinLTO for example.
