Adding old unit tests to test suite.

These tests are copied straight over. They'll still run, but they're
using the old system.

+This is a miscellaneous test that was imported into the new-at-the-time
+runtime test framework. The test is intended to exercise basic features,
+and as such cannot be build on top of junit, since failure of such basic
+features might disrupt junit.

+TODO: Real description goes here.
