mergecopies: invoke _computenonoverlap for both base and tca during merges

The algorithm of _checkcopies can only walk backwards in the DAG, never
forward. Because of this, the two _checkcopies patches need to run from
their respective endpoints to the TCA to cover the entire subgraph where
the merge is being performed. However, detection of files new in both
endpoints, as well as directory rename detection, need to run with respect
to the merge base, so we need lists of new files both from the TCA's and
the merge base's viewpoint to correctly detect renames in a graft-like
merge scenario.
