* omp-low.c (maybe_lookup_decl): Constify first argument.
(use_pointer_for_field): Change last argument from bool to
omp_context *. Disallow shared copy-in/out in nested
parallel if decl is shared in outer parallel too.
(build_outer_var_ref, scan_sharing_clauses,
lower_rec_input_clauses, lower_copyprivate_clauses,
lower_send_clauses, lower_send_shared_vars): Adjust callers.
* testsuite/libgomp.c/pr35549.c: New test.
