Description
Simplify MinMaxRed_Long test by making arrays contain random data.

The current implementation of the test distributes the data in the arrays in order to achieve certain degree of branch levels, but this is only matters for situations in which vectorization doesn't kick in. This test specifically covers situations when vectorization comes into play. Therefore, the added complexity to distribute the data in the arrays does not add anything to the test.
