Run this check on all alternates, as well. We use a new process for two reasons: 1. The subcommand decouples the details of loading and verifying a commit-graph file from the other fsck details. 2. The commit-graph verification requires the commits to be loaded in a specific order to guarantee we parse from the commit-graph file for some objects and from the object database for others.
