Subzero: Validate phi instructions after CFG construction. It checks that each phi label corresponds to an incoming edge, and that each incoming edge has a corresponding phi label. It does not check that duplicate incoming edges get the same phi value. Performance impact is minimal (~0.2%) despite the O(N^2) implementation.
