Alternative approach -- introduce a special forward propagation before or after
the ivopt to get rid of the redundant iv. This propagation needs to propagate
through header phi.

The issue here is that loop header copying creates a new induction variable
by moving the use before the definition of D.2708_4 = start_3(D) + i_12.
So it just does what we teach PRE not to do ...

Confirmed. Another way is to move loop header copying before FRE.
