g|_ndS(sLRemove bogus edge for unconditional transfers

        Each block has a next edge that accounts for implicit control
        transfers, e.g. from a JUMP_IF_FALSE to the block that will be
        executed if the test is true.

        These edges must remain for the current assembler code to
        work. If they are removed, the dfs_postorder gets things in
        weird orders.  However, they shouldn't be there for other
        purposes, e.g. conversion to SSA form.  This method will
        remove the next edge when it follows an unconditional control
        transfer.

    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.
