I have included the current state of my patch. All task-detach-* tests pass when

Nvidia, task-detach-6.* hangs consistently but everything else passes (probably
because of the missing gomp_team_barrier_done?).
It looks like the hang has nothing to do with the detach patch - this hangs
consistently for me when offloaded to NVPTX:
#include <omp.h>
int main (void)
{
#pragma omp target
#pragma omp parallel
#pragma omp task
;
}
This doesn't hang when offloaded to GCN or the host device, or if num_threads(1)
is specified on the omp parallel.
