[plt-dev] Change to `check-expect' implementation

In the process of adding types for `check-expect', I realized that the
expansion of the `test' form could be made much simpler, by simply
expanding into a function that does the relevant work.  This also
makes it much easier to typecheck.  I've attached a patch that does
this - it passes all of the test-engine tests as well as the tests for
the interaction between the stepper and `check-expect'.

Is this ok to commit?
