CodeGen: address post commit review comments for r291123

This test would force the execution of the backend.  However, the
backend already has a test for this.  Effectively, this was trying to
test that an API call was made properly.  We do not have a good way to
really test this.  The test itself tested very little.

Addresses post-commit review comments from Eric Christopher.
