-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.
-
-This test covers the string inline-execute tests, and it done in a
-looping manner to ensure that the tests are translated when a Jit is
-active.
