Fix class type subtyping
...
Although classes have no non-trivial subtyping relationships,
the representation I chose ends up introducing cases where two
"equal" types are not represented in the same way. This
commit fixes that by checking only the relevant parts of the
representation.

Implement row polymorphism
...
- Refactor syntax classes and parsing for class types in
order to accommodate constraints for row polymorphism
- No contract generation, but other parts are implemented

Now `super-new` calls are type-checked with the right
context so that init arguments can be passed as arguments.
In addition, the `super-new` checking was factored out into
three functions.
