          Components: DRLVM
         Environment: Any

         Attachments: hir_liveness.patch

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.
