(Yet, you might see the reduction clause among others in the data operands of the compute constructs. This PR does not change the situation. The order of data-action operands means nothing as described in https://github.com/llvm/llvm-project/pull/139723. It is a user's responsibility to consider the order of the data operands of the compute constructs.)
