[flang-commits] [flang] [flang][OpenMP] Lower DO and SIMD variants in metadirectives (PR #210810)

Thanks for advancing metadirective loop lowering. The associated-loop splicing and the per-candidate DSA guard are cleanly structured, and the `Todo/` tests cover the unsupported cases thoroughly. I built the patch and ran a few reproducers, and five questions came up. They are mostly about the loop-only checks running before variant selection, plus one configuration that triggers an assertion.
