Title: Added new TestCase helper; E4X test(s) for bug 687303

I added a new `TestCase` class in the test helpers. I'll use this during my upcoming refactor to help rewrite the tests to be less awful. I also used it for the E4X tests.

The E4X tests simply allow the validator to iterate the E4X nodes in the parse tree, which makes any Expression nodes that may be within them visible.
