Records can be constructed, returned, and field accessed in non-dynamic code. Type checks don't work, so records cannot be added to generic collections like `List<(int,int>)`.
- Add runtime for base classes for records of various arities.
- Use impacts to collect record static types used.
- Create record classes for each record shape. Record classes have
extra metadata properties on the prototype. This allows slower,
general operations at the root of the hierarchy that can be
overridden with specialized operations lower in the hierarchy.

- Support interface types without generic parameters in type tests.
- Add '|' symbol to recipes to separate the library identifier from
the type. This is used in the modular setting where types are not
guaranteed to have a unique name.
- Add a runtime method to strip library identifiers when printing
type names.
- Add a runtime method to retrieve original Dart type name from
constructors.
