Congzhe Cao 05ccde8023 [LoopCacheAnalysis] Fix a type mismatch problem in cost calculation ... There is a problem in loop cache analysis that the types of SCEV variables `Coeff` and `ElemSize` in function `isConsecutive()` may not match. The mismatch would cause SCEV failures when `Coeff` is multiplied with `ElemSize`. The fix in this patch is to extend the type of both `Coeff` and `ElemSize` to whichever is wider in those two variables. As a clean-up, duplicate calculations of `Stride` in `computeRefCost()` is then removed.
