> Liveness analyzer for HIR. Validates liveness, dumps liveness info into the dot file.
> Works on the non-SSA representation. Don't use after translator in inliner session -
it will break because of method parameter copying in inliner.
> Add "liveness" pass in the optimizer pipeline after translator. tested on a few test
cases and passed "ant test" on Win32/debug build with liveness check after translator.
