    dwarf: emit DW_AT_name for DW_TAG_GNU_formal_parameter_pack [PR70536]

    Per https://wiki.dwarfstd.org/C++0x_Variadic_templates.md
    DW_TAG_GNU_formal_parameter_pack should have a DW_AT_name:

    17$:      DW_TAG_formal_parameter_pack
                  DW_AT_name("args")
    18$:          DW_TAG_formal_parameter
                      ! no DW_AT_name attribute
                      DW_AT_type(reference to 13$)
    (...)
