Once again, this is a clause on a combined construct that does almost exactly what the loop/compute construct version does, only with some sl ightly different evaluation rules/sema rules as it doesn't have to consider the parent, just the 'combined' construct. The two sets of rules for reduction on loop and compute are fine together, so this ensures they are all enforced for this too. The 'gangs' 'num_gangs' 'reduction' diagnostic (Dim>1) had to be applied to num_gangs as well, as it previously wasn't permissible to get in this situation, but we now can.
