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
