Significantly cut memory usage and SQL queries when reloading diffs
By preloading certain models with the diff, we can eliminate many N+1
queries. For a push to the staging GitLab.com www-gitlab-com repository,
this eliminates over 3000 SQL queries and appears to bring down the RSS
usage by several gigabytes.
