Implemented path-exploration based live ranges construction
...
The algorithm is based on "Computing Liveness Sets for SSA-Form Programs",
Florian Brandner, Benoit Boissinot, Alain Darte, Benoit Dupont de Dinechin,
Fabrice Rastello. TR Inria RR-7503, 2011
In comparison to the existing bitset based approach, the new algorithm
is more memory-space efficient and faster on big functions.

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.
