          Generates a series of Instruction named tuples giving the details of
          each operations in the supplied code.
  
          If *first_line* is not None, it indicates the line number that should
          be reported for the first source line in the disassembled code.
          Otherwise, the source line information (if any) is taken directly from
          the disassembled code object.
