Rollup merge of #145672 - compiler-errors:query-instab-ice, r=lcnr

Instantiate higher-ranked binder with erased when checking `IntoIterator` predicate for query instability

Fixes https://github.com/rust-lang/rust/issues/145652 which was introduced by https://github.com/rust-lang/rust/pull/139345 because we were skipping a binder before calling `Instance::try_resolve`.
