Addressed issues I alluded to in my previous comment.

This revision completely separates the decision to scalarize an induction variable from the logic in collectLoopUniforms and collectValuesToIgnore. The  need to do this became apparent after better defining what we mean by uniform (see the added comment above the collectLoopUniforms declaration). Since scalar doesn't imply uniformity, it doesn't make sense to use collectLoopUniforms to determine which induction variables will be scalar.
