* omp-low.c (lookup_decl_in_outer_ctx): Allow calling this
with !ctx->is_nested.
(maybe_lookup_decl_in_outer_ctx): Look up in outer contexts
even if !ctx->is_nested.
(lower_copyprivate_clauses, lower_send_clauses,
lower_send_shared_vars): Call lookup_decl_in_outer_ctx
unconditionally.
* testsuite/libgomp.c/private-1.c: New test.
