> UnreachableCodeElimination and DeadCodeElimination passes should go
> in the 'DCE,UCE' order, not in the opposite one.
> DCE  eliminates some dead code and remove empty nodes.
> This activity can produce unreachable nodes (Unreachable means that there is no path
> from entry node to the considered one). The ControlFlowGraph with unreachable nodes
> is invalid and some HLO passes crashes when working on such kind of CFG.
> UCE pass fixes this invalidity by moving unreachable nodes out from the CFG.
> The issue depends on HARMONY-1417
