This patch moves GOMP_MAP_ATTACH{_ZERO_LENGTH_ARRAY_SECTION} nodes to
the end of the clause list, for offload regions. This ensures that when
we do the attach operation, both the "attachment point" and the target
region have both already been mapped on the target. This avoids a
pathological case that can otherwise happen with struct sibling-list
handling.
This version of the patch moves the attach-node motion to
gimplify_adjust_omp_clauses.
