* Types: Avoid comparing IDs for in Type::IsSameImpl When linking, we end up with duplicate types for imported and exported types, that needs to be removed. The current code would reject valid import/export pairs of symbols due to IDs mismatch, even if the types or constants behind those ID were the same. Enabled remaining type_match_test Fixes #2442
