Avoid sorting by DefId for `necessary_variants()` Follow-up to rust-lang#83074. Originally I tried removing `impl Ord for DefId` but that hit *lots* of errors 😅 so I thought I would start with easy things. I am not sure whether this could actually cause invalid query results, but this is used from `MarkSymbolVisitor::visit_arm` so it's at least feasible. r? `@Aaron1011`

Isn't FxIndexSet preserve insertion order, but FxHashSet only use custom hasher? Ah, hashset used only to check duplicates, my bad. |
