Use range analysis for better trip count analysis Rationale: Marking more loops as always-taken avoids generating unnecessary new top tests while marking more loops are non-infinite enables more optimizations. This CL helps with these improvements. Also, some more code is shared between induction and range analysis and a bug with refining ranges has been fixed.
