        actual literal, fix this

b0769c5f1a sysf: impl renaming of forall binders but then backed out 
- capture when applying forall is ok since binder is renamed as well
  - and since type names are valid binder names, this is ok
  - TODO: what if we call inst with non-base type?
- add more variable capture tests
- typecheck: type= handles alpha-equiv

ea5d41deb0 sysf: code cleanup 
- at this point, sysf only extends define-type, app, and lambda
- sysf passes all stlc-tests and sysf-tests

b49ddbaabf stlc: fix some bugs 
- provide assert-Unit-type and assert-Int-type, for sysf
  - sysf must use these instead of its own because type= relies on
    free-identifier=?, so it must be comparing the same Int type
- move tests to the end
- define-type syntax class must declare define-type as a datum-literal
  and not a literal, otherwise the wrong version will get used when
  another language extends define-type
