openmp: Fix ICE in [PR103705]
Fix ICE for cases like:
#pragma omp target update from(s[0].a[0:1])
where multiple ARRAY_REF nodes exist and require more than one peeling
during [c_]finish_omp_clauses.
PR c++/103705
gcc/c/ChangeLog:
* c-typeck.c (c_finish_omp_clauses): Also continue peeling off of
outer node for ARRAY_REFs.
gcc/cp/ChangeLog:
* semantics.c (finish_omp_clauses): Also continue peeling off of
outer node for ARRAY_REFs.
gcc/testsuite/ChangeLog:
* c-c++-common/gomp/pr103705.c: New test.

Can this be closed? Or is something in addition still needed?
(It is marked as GCC 12 regression and I see one mainline/GCC12 commit for it.)
