Hahnfeld added a dependency: D51786: [libomptarget-nvptx] Add tests for nested parallelism.

According to OpenMP 4.5, p250:12-14:

  If the requested nest level is outside the range of 0 and the
  nest level of the current thread, as returned by the omp_get_level
  routine, the routine returns -1.

The SPMD code path will need a similar fix.
