        * dwarf2out.c (field_byte_offset): Restore the
        PCC_BITFIELD_TYPE_MATTERS behavior for INTEGER_CST DECL_FIELD_OFFSET
        and DECL_FIELD_BIT_OFFSET.  Use fold_build2 instead of build2 + fold.
        (analyze_variants_discr, gen_variant_part): Use fold_build2 instead
        of build2 + fold.
