f5b7065b10 Refactor the ENTRY nodes 
Now all ENTRY nodes have a "fake" input control edge.
Through this edge all of them are dominated by START node.

6a4e239773 Create a sparate pass to remove unreachableble CFG blocks. 
SCCP pass removes unreachable blocks before CFG construction.
In case of -O0 or -O1 pipeline (without SCCP) it's simpler and faster
to unlink unreachable CFG blocks once, then check for reachability
in almost any compilation pass.
-O2 pipeline (with SCCP) don't need this pass.

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.
