Reorganize functions for type parameters
...
This refactoring saves some lines and reduces the ridiculous
number of arguments for some helper functions. (using a hash
table instead of arguments) This will help for adding type
parameter name scoping later.

Add support for separate augment/pubment interfaces
...
Now a class may have a pubment method that has a different
type for being directly called and for being specialized
for inner calls. This is actually necessary to type-check
interesting uses of pubment/augment.
Note that if a class does not provide a type annotation
for the augmentation interface, it will be assumed to be
the same as the pubment type.

Procedure, TR will try to find a more precise type and

This required changes to the type and row

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.
