Add minimal support for DW_TAG_GNU_template.

http://gcc.gnu.org/wiki/TemplateParmsDwarf describes
DW_TAG_GNU_template_template_param, DW_TAG_GNU_template_parameter_pack,
DW_TAG_GNU_formal_parameter_pack and DW_AT_GNU_template_name.
Added to libdw/c++/dwarf-knowledge.cc, dwarflint/expected-at.cc and
dwarflint/dwarf_gnu.cc
