This, together with bitops2 and endians2, forms the core primitive
offering for working with integers as the computer sees them.

The focus of intops is to expose a number of common integer operations
typically used to build more complex abstractions such as bigints,
mp-ints etc while having access to the best performance the compiler and
cpu can offer.

There is more to do here, but this provides an outline of what this
module could look like.

Obviously, there are no exceptions or defects around - the point of
these utilities is to stay as close as possible to bare metal. They
could be used to implement such features however (similar to how
`system/integerops` works).
