    This class builds the lnotab, which is documented in compile.c.
    Here's a brief recap:

    For each SET_LINENO instruction after the first one, two bytes are
    added to lnotab.  (In some cases, multiple two-byte entries are
    added.)  The first byte is the distance in bytes between the
    instruction for the last SET_LINENO and the current SET_LINENO.
    The second byte is offset in line numbers.  If either offset is
    greater than 255, multiple two-byte entries are added -- see
    compile.c for the delicate details.
