[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.
