[flang-commits] [flang] [flang][OpenMP] Split check-omp-structure.cpp into smaller files, NFC (PR #146359)

How bad is the impact on flang build time? From what I remember from when OpenMP lowering was split, the compilation file of each translation unit was so dominated by processing the headers that adding `n` translation units roughly increased compilation time of that part by a factor of `n`.

But that aside I think this is a good idea from a code design perspective.

Please could you add a comment at the top of each file documenting what should go in that file (just the text from the commit message would be fine).
