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.
