[PATCH v3 0/1] And so it begins...merge/rename performance work

This depends on a merge of en/ort-conflict-handling, en/diffcore-rename,
and en/ort-directory-rename.

Changes since v2:
  * Add another step I forgot in my testcase setup -- setting
    merge.directoryRenames (noticed by Sangeeta); I've double checked
    that I didn't forget any other settings.

  merge-ort: begin performance work; instrument with trace2_region_*
    calls
