        Currently, the global object is being embedded in the JavaScriptCore
        bytecode, however since the global object is the same for all opcodes
        in a code block, we can have the global object just be a member of the
        associated code block.

        Additionally, I added an assert inside of emitOpcode that verifies
        that the last generated opcode was of the correct length.

            correct length.

            Changed the last opcode to op_end since the length will no longer
            be correct.
