Thanks @bhandarkar-pranav @tblah for your comments. I have pushed a commit that uses `DeadCodeAnalysis`. It makes the code a bit simple because that analysis can handle both constant if conditions and block level reachability. Please have a look. We can either use this or revert this commit and can do back to Dominance based analysis.
