Carl Meyer ea1aa9ebfe [ty] use interior mutability in type visitors (#19871) ... ## Summary Type visitors are conceptually immutable, they just internally track the types they've seen (and some maintain a cache of results.) Passing around mutable visitors everywhere can get us into borrow-checker trouble in some cases, where we need to recursively pass along the visitor inside more than one closure with non-disjoint lifetime. Use interior mutability (via `RefCell` and `Cell`) inside the visitors instead, to allow us to pass around shared references. ## Test Plan Existing tests.		2025-08-11 15:42:53 -07:00
