Expand description

Builds the DW_TAG_variant_part of an enum or coroutine debuginfo node:

      DW_TAG_structure_type              (top-level type for enum)
--->    DW_TAG_variant_part              (variant part)
          DW_AT_discr                    (reference to discriminant DW_TAG_member)
          DW_TAG_member                  (discriminant member)
          DW_TAG_variant                 (variant 1)
          DW_TAG_variant                 (variant 2)
          DW_TAG_variant                 (variant 3)
        DW_TAG_structure_type            (type of variant 1)
        DW_TAG_structure_type            (type of variant 2)
        DW_TAG_structure_type            (type of variant 3)
