This is just to get an upper bound to the perf overhead associated with fixing #99682. We could be a bit more clever and only perform collection, not partitioning, or even more clever and do "mentioned items" collection rather than full collection (when #122568 lands) -- but for now let's just get a ballpark number.

So the information to do this is simply not present because we don't store the MIR of things in rmeta files, or something like that? To to make this approach work I think we'd have to (a) make "mentioned items" traversal work without full MIR (based on Oli's proposal of a separate query that just returns the mentioned items), and then (b) do a mentioned items traversal of everything (rather than the usual used items traversal) in a check build.
