"git checkout -m -- path" uses the unmerge_marked_index() API, whose implementation is incapable of unresolving a path that was resolved as removed. Extend the unmerge_index() API function so that we can mark the ce_flags member of the cache entries we add to the index as unmerged, and replace use of unmerge_marked_index() with it. Now, together with its unmerge_index_entry_at() helper function, unmerge_marked_index() function is no longer called by anybody, and can safely be removed. This makes two known test failures in t2070 and t7201 to succeed.
