diff-index --cached --raw: show tree entry on the LHS for unmerged entries.
This updates the way diffcore represents an unmerged pair
somewhat. It used to be that entries with mode=0 on both sides
were used to represent an unmerged pair, but now it has an
explicit flag. This is to allow diff-index --cached to report
the entry from the tree when the path is unmerged in the index.
This is used in updating "git reset <tree> -- <path>" to restore
absense of the path in the index from the tree.
