REVISION SUMMARY
  The intent is clearly to have `calculateupdates()` figure out what
  actions need to be taken and `recordupdates()` to make necessary
  modifications to the dirstate. However, in the
  `ACTION_PATH_CONFLICT_RESOLVE` case, there was one little inspection
  of copy information done in `recordupdates()`. This patch moves that
  to `calculateupdates()`. That will help with the next patch, which
  makes `merge.update()` work better with `overlayworkingctx` (copies
  should be recorded there too, even though we skip the
  `recordupdates()` step).
