Test that the emulator doesn't throw until the userop is actually encountered at run time.

<p>
NOTE: The userop must be defined by the language, but left undefined by the library.
Otherwise, we cannot even compile the sample Sleigh.

<p>
NOTE: Must also use actual instructions, because the test passage constructor will fail fast
on the undefined userop.
