openmp: Fix ICE in [PR103705]

Browse Source 
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.
