Use TTG empty extensions to remove some `error`'s
None of these error cases should ever have been reachable, so this is
just a matter of leveraging the type system to assert this.
* Use the `NoExtCon` and `noExtCon` to handle case matches for no
extension constructors, instead of throwing an `error`.
* Use the extension field of `HsSpliceTy` to ensure that this variant
of `HsType` cannot exist in an `HsType DocNameI`.
