* Implement ignoring the difference between `Self as` and `as`, as well as `where` clauses at the end of an `impl` declaration when checking whether `impl` declarations match, from #3763. * Allow impl declarations with different constraint ids to match, as long as the facet type of the constraint has the same interface_id and specific_id. * Add some TODOs reflecting future facet type resolution. --------- Co-authored-by: Josh L <josh11b@users.noreply.github.com>
