        <pre>The runtime should stop for the following code, instead of treating the
transfer as no-op and running through.

int main()
{
  int a[10];
  #pragma omp target enter data map(alloc: a[:10])
  #pragma omp target update to(a[:20])
  #pragma omp target exit data map(delete: a[:10])
}

Libomptarget --> Looking up mapping(HstPtrBegin=0x00007ffe3fe353f0, Size=80)...
Libomptarget --> WARNING: Pointer is already mapped but section extends beyond
mapped region
Libomptarget --> hst data:0x00007ffe3fe353f0 not found, becomes a noop

Let me know if the OpenMP specification explicitly says this is the intended
behavior.</pre>
