…i-obk Check freeze with right param-env in `deduced_param_attrs` We're checking if a trait (`Freeze`) holds in a polymorphic function, but not using that function's own (reveal-all) param-env. This causes us to try to eagerly normalize a specializable projection type that has no default value, which causes an ICE. Fixes rust-lang#110171
