The insert_stage_data() fallback becomes much more important for directory rename detection, because that creates a mechanism to have a file in the resulting merge that didn't exist on either side of history. However, insert_stage_data(), due to calling get_tree_entry() loaded up trees as readily as files. We aren't interested in comparing trees to files; the D/F conflict handling is done elsewhere. This code is just concerned with what entries existed for a given path on the different sides of the merge, so create a get_tree_entry_if_blob() helper function and use it.
