Chad Rosier bf29f811c5 [LV] Use Demanded Bits and ValueTracking for reduction type-shrinking ... The type-shrinking logic in reduction detection, although narrow in scope, is also rather ad-hoc, which has led to bugs (e.g., PR35734). This patch modifies the approach to rely on the demanded bits and value tracking analyses, if available. We currently perform type-shrinking separately for reductions and other instructions in the loop. Long-term, we should probably think about computing minimal bit widths in a more complete way for the loops we want to vectorize.
