Adding more potential reviewers. I'm not sure if anyone is familiar with this code, but others definitely have a better understanding of the data structures than me.

Also note that we got confirmation in PR47395 that the compile time went from 12 hours (!) back to 3 minutes, so this patch does solve the motivating bug.
