  Log Message:
  -----------
  assert-instance?, assert-not-instance?

This brings assert-instance? and assert-not-instance? macros to the newer
assert-based macros. These can be used to get better test failure output
when an assertion fails (rather than assert-true(instance?(...)) or
assert-false(instance?(...))).

* assertions.dylan
  (do-check-instance?): Add negate? flag to handle ~instance? as well.
  (check-instance?): Pass #f for negate? to do-check-instance?.
  (assert-instance?, assert-not-instance?): New macros.

* library.dylan
  (module testworks): Export assert-instance?, assert-not-instance?.

* documentation/users-guide/source/reference.rst
  (assert-instance?, assert-not-instance?): Document.
  (check-instance?): Correct terminology: type, not class.

* documentation/users-guide/source/usage.rst
  (Assertions): Link to new assertions.

* tests/specification.dylan
  (module-spec testworks): Mention new assertions and stub tests.

* tests/testworks-test-suite.dylan
  (testworks-assert-instance?-test,
   testworks-assert-not-instance-test): Test new assertions. We test these
     here to be consistent with the other assertion tests. In the future,
     this could move to the testworks specifications tests.
  (testworks-assertion-macros-suite): Run the new tests.
