57a76517fc Enable environment extension in unit tests 
This allows a unit test like tc-e to extend the lexical
type environment when checking the test expression.

33543ce054 Use absent in some row poly class contracts 
When exporting row polymorphic functions from TR, just
use absent clauses to ensure that TR won't accidentally
try to add pre-existing fields/methods. No sealing is
needed because the typechecker enforces parameteric use
of the class.

8d0c352dcc Add a custom object contract for use in TR 
This corresponds to the more strict object contracts
from the OOPSLA paper. Also use `object/c-opaque` in
TR contract generation

ec15f58542 Basic support for contract gen for PolyRow types 
Currently only supports the typed export side. The other
way needs contract features that haven't been merged yet.

888893d81b Work around type alias printing limitations 
Type aliases in internal definition contexts can affect
type printing outside of the context, which can cause
interference in unit tests.

This only seems to happen when running with the TR test
driver.

62c86d5ddd Added occurrence typing for private fields. 
This also tracks mutation of private fields to ensure that only
non-mutated field types are allowed to be refined.

6c09d52b2e Generalize method handling in TR 
Previously, TR only recognized a subset of the syntax that
the class macro accepts for method definitions (and errored
unhelpfully on other cases). Though that subset was sufficient
for most methods, macros will sometimes produce unusual forms.

9d41048747 fixed mutation let-aliasing bug 
let-aliasing initially forgot to check if a variable that might act as
an alias was ever mutated. fixed by disallowing a mutated variable to
act as an alias.

6059fb481b Check expected type before calling tc/funapp1 
This compensates for a change in commit bb3f446186
that made the possible-domains function more permissive
(possibly returning results that are inconsistent with the
 expected type).
