  Log Message:
  -----------
  [flang][OpenACC] Don't emit unstructured-loop TODO for wrappable loops

`genOpenACCLoopFromDoConstruct` raised an NYI for any unstructured DO inside `acc kernels`. That check ran before the wrapping in `genFIR(DoConstruct)`, so a loop whose CFG is self-contained aborted lowering even though the fall-back path would have wrapped it in an `scf.execute_region`.

Skip the TODO when `isWrappableConstruct()` accepts the loop. Such a loop is not attached to a directive; it is only nested inside the kernels region.
