        Description

        Phi nodes are generated when needed to represent instance's fields values to scalar
        replace an allocation. They are generated during memory optimization by using
        split_through_phi optimization. It creates problem when we do this for loop's Phi
        since there is no a guard against infinite (for each optimization path for the loop)
        generation of such values Phi nodes.
