Make is/isnt handle expected type objects properly
Make is/isnt handle expected type objects properly

Instigated by [Tux]++, it seemed like a good idea to handle type objects as
the "expected" value of an is/isnt differently from defined values.  So, now
the logic is:

- if got/expected have a defined/undefined mismatch, it is a Fail
- if got/expected are both type objects (undefined), use === for comparison
- if got/expected are both defined, use eq for comparison (as before)

This change brings out quite some faulty tests out of the woodwork.
