This revision is now accepted and ready to land.

Now that `target nowait` operations are handled via hidden helper tasks which make sure that dependencies are satisfied, these calls to `__kmpc_omp_taskwait` are not only redundant but also hurt performance as they serialize execution unconditionally. LGTM. Can you edit the patch description and explain exactly what you mean and why this patch is needed? Thanks!
