Note that for methods, if the type is annotated as
Procedure, TR will try to find a more precise type and
use that instead.

Support pubment and augment methods
...
This required changes to the type and row
representation. I also got rid of the redundancy
between Row and Class types.
Some other bugs had to be quashed for these
changes, such as private methods not actually
being type-checked.

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.

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
