omp cleanup

[Nathan Sidwell]

Jakub,
looking at the next thing to merge, I stumbled on code in lower_omp_target that 
appears at least confused.

we have:
   if (offloaded || data_region)
     {  A }
   else if (data_region)
     new_body = tgt_body;
   if (offloaded || data_region)
     { B }

which can clearly be simplified to:

    if (offloaded || data_region)
      { A; B; }

If that's incorrect, is the first '|| data_region' wrong?
