From 0f304d2d898259f61418bdabdb83572579791674 Mon Sep 17 00:00:00 2001
From: Daniel Ellison <daniel@syrinx.net>
Date: Tue, 6 Dec 2016 11:11:57 -0500
Subject: Removed 'panic' from 'constructor_arguments_external' and added
 specific test for fallback and fallthrough. Added one test for 'lit'. Added
 tests for arithmetic/binary/unary operations. Added the start of tests for
 assembler instructions within LLL source.
