Summary: This pass was assuming that when a PHI instruction defined a register used by another PHI instruction that the defining insstruction would be legalized before the using instruction. This assumption was causing the pass to not legalize some PHI nodes within divergent flow-control. This fixes a bug that was uncovered by r285762.
