DomTree: Make PostDomTree indifferent to block successors swap
Fixed the commit c35585e209efe69e2233bdc5ecd23bed7b735ba3.
This is a fix for the bug 46098 where PostDominatorTree
is unexpectedly changed by InstCombine's branch swapping
transformation.
This patch fixes PostDomTree builder. While looking for
the furthest away node in a reverse unreachable subgraph
this patch runs DFS with successors in their function order.
This order is indifferent to the order of successors, so is
the furthest away node.
