Graphite generates MAX/MIN expressions.
I've modified Graphite to use the original types of "n" and "mid" in MIN and
MAX, and to not generate the casts of "n" and "mid" to a longer signed INT
before MIN/MAX, and the vectorization succeeded.
It seems that it is not a Graphite problem but a scalar evolution one. Scalar
evolution is not able to handle MIN/MAX expressions in the presence of casts.
Beside vectorization also further unrolling is prevented.
