semantics.c (handle_omp_array_sections_1): Don't ICE when processing_template_decl when checking for bitfields and unions.

	* semantics.c (handle_omp_array_sections_1): Don't ICE when
	processing_template_decl when checking for bitfields and unions.
	Look through REFERENCE_REF_P as base of COMPONENT_REF.
	(finish_omp_clauses): Look through REFERENCE_REF_P even for
	array sections with COMPONENT_REF bases.

	* testsuite/libgomp.c++/target-21.C: New test.
