  This is a series of patches to support deep struct dereferences for
OpenMP 5.0 (i.e. with multiple arrow operators,
"a->b[foo]->c[lo:hi]"). Apart from a couple of general bug fixes, the
main parts of this comprise:

  1. Topological sorting of OMP clauses by base pointer dependencies.

  2. Hoisting of struct sibling list handling out of
     gimplify_scan_omp_clauses.

These patches replace and continue from the last part of the
previously-posted series:

  https://gcc.gnu.org/pipermail/gcc-patches/2021-August/577219.html

and (still) depend on the parts of 1 through 7 of that series.

The patches have been bootstrapped & regression tested individually with
offloading to NVPTX (though some prior to the most recent rebase).

OK?

Thanks,

Julian
