76f44fa126 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.

56b0dbccde Use ir_ctx.mflags for CPU specific code-generation options 
'mflags' and ir_cpuinfo() return value have the same meaning.

d07a2db592 Improve GCM to schedule floating nodes that depends only on constants 
(e.g. COPY(CONST)) to the last common ancestor.

Previously these nodes went to the first block.

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.
