diffcore-rename: limit dir_rename_counts computation to relevant dirs
We are using dir_rename_counts to count the number of other directories that files within a directory moved to. We only need this information for directories that disappeared, though, so we can return early from update_dir_rename_counts() for other paths. If dirs_removed is passed to diffcore_rename_extended(), then it provides the relevant bits of information for us to limit this counting to relevant dirs. If dirs_removed is not passed, we would need to compute some replacement in order to do this limiting. Introduce a new info->relevant_source_dirs variable for this purpose, even though at this stage we will only set it to dirs_removed for simplicity.
