We need to rewrite the index file when we check out files, even if we haven't modified the blob info by reading from another tree, so that we get the stat cache to include the fact that we just modified the file so it doesn't need to be refreshed. While we're at it, move everything that needs to be done to check out some paths from a tree (or the current index) into checkout_paths().
