Jira issue: CRDB-68501

Start at query_comparison_util.go:501 and read the roachtest README for the investigation workflow. Use the linked TeamCity artifacts and logs to investigate the unoptimized-query-oracle failure and compare the reported optimized and unoptimized results. Done means the seed-multi-region test no longer reports unequal results.
