Test reading from a variable in an unreachable block.

<p>
Yes, this test is valid, because, even though no slaspec should produce this, they could, but
more to the point, a user injection could. Note that the underlying classfile writer may
analyze and remove the unreachable code. Doesn't matter. What matters is that it doesn't
crash, and that it produces correct results.
