The bug is in redphi1
Since we are not running iterating dom at -O1, we get two phi's which can be reduced and one of them
causes a call expression to be foldded and then we don't update the use infromation for the other
SSA_NAMEs. And this caues us not to be able to propagate the other SSA_NAME from the other PHI.
CCing Steven since he was the one who turned off iterating dom at -O1.
