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.
