And the following testcase shows similar issues in the array section
handling path.
Tested on x86_64-linux and i686-linux, plus with intelmicemul offloading,
committed to trunk.

        * 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.
