Dylan DPC 9cfd161cd5 Rollup merge of #99928 - compiler-errors:issue-99914, r=oli-obk ... Do not leak type variables from opaque type relation The "root cause" is that we call `InferCtxt::resolve_vars_if_possible` (3d9dd681f5) on the types we get back in `TypeError::Sorts` since I added a call to it in `InferCtxt::same_type_modulo_infer`. However if this `TypeError` comes from a `InferCtxt::commit_if_ok`, then it may reference type variables that do not exist anymore, which is problematic. We avoid this by substituting the `TypeError` with the types we had before being generalized while handling opaques. This is kinda gross, and I feel like we can get the same issue from other places where we generalize type/const inference variables. Maybe not? I don't know.
