I am not completely sure whether you had the following in mind, but
that's what I have now implemented:
   DEFTREECODE (RANGE_FOR_STMT, "range_for_stmt", tcc_statement, 4)
has now a 5th operator (RANGE_FOR_IVDEP), which has the value
boolean_true_node - or NULL_TREE (via begin_range_for_stmt).

You don't need to add an operand, you can use one of the TREE_LANG_FLAGs 
for a boolean flag.
