Now that we have changes introduced by #145837, mapping reductions from `do concurrent` to OpenMP is almost trivial. This PR adds such mapping. PR stack: - https://github.com/llvm/llvm-project/pull/145837 - https://github.com/llvm/llvm-project/pull/146025 - https://github.com/llvm/llvm-project/pull/146028 - https://github.com/llvm/llvm-project/pull/146033 (this one)
