b56f1f5298 Refactor CFG construction algorithm to mark all BB starts in two passes. 
First we perform a backwad DFS search from "stop" nodes. This pass may
leak some CFG paths ended by infinite loops. To support these paths we
record their possible roots and perform forward DFS search starting from
them.
