------------------------------------------------------------
For the record, {{libdivide}} may be useful for optimal integer division
performance.

NOTE: this is only for {{vector/scalar}}, when there's only one divisor.

> Add a pair of binary kernels to compute the:
> * quotient (result after division, discarding any fractional part, a.k.a
> integer division)
> * mod or modulo (remainder after division, a.k.a {{%}} / {{%%}} / modulus).
> The returned array should have the same data type as the input arrays or
> promote to an appropriate type to avoid loss of precision if the input types
> differ.
