cpumask: Introduce cpumask_intersects_and
Introduce bitmap_intersects_and() to determine whether the intersection
of three bitmaps is non-empty. Unlike cpumask_first_and_and(), this
returns immediately when an intersecting word is found and does not
calculate the first matching bit.
Add cpumask_intersects_and() as the corresponding cpumask wrapper.
A subsequent patch uses the helper to determine whether a task
has a CPU that is present in its affinity mask, the preferred CPU mask,
and task possible CPU mask.
