  [AArch64][NFC] Add test as a representative of scalarizing a vector i… (#114107)

…nteger division

The last resort to vectorize a bundle of integer divisions is considered
scalarizing it. Currently, the cost estimates for scalarizing a vector
division can be considerably overestimated as is the scenario with this
motivating test case i.e. vector cost should not deviate much from the
scalar cost.

Future patch will try to improve the scalarization cost.
