Various induction/range analysis improvements.

Rationale: this change list improves analysis of triangular loops
           both by changing loop order for induction analysis
           (enabling range analysis in inner loops) and by
           some symbolic improvements during range analysis;
           also, a mul/div bug has been fixed (with pass/fail
           unit tests); lastly this change list prepares some
           follow up optimizations.
