This revision is now accepted and ready to land.

I suppose the same must be applied to all cases where `present` is used. Without a modification like this, `present` just confirms that the starting address of the object is already mapped, although a size may be specified in the map clause.

  #pragma omp target map(present: p[0:10]) // present will succeed even if only p[0] is mapped and p[1]-p[9] are not

So the question here is: should `present` apply to the size as well as the begin address? I would say yes.
