IDF is done. This is used by passes that need the PHI nodes for
O_j even if it means that some arguments will come from the default
definition of O_j's symbol (e.g., pass_linear_transform).

WARNING: If you need to use this flag, chances are that your pass
may be doing something wrong. Inserting PHI nodes for an old name
where not all edges carry a new replacement may lead to silent
