Dan Gohman aa03649af2 Extend the IndVarSimplify support for promoting induction variables: ...

- Test for signed and unsigned wrapping conditions, instead of just
   testing for non-negative induction ranges. 
 - Handle loops with GT comparisons, in addition to LT comparisons.
 - Support more cases of induction variables that don't start at 0.
