This looks pretty straightforward, I've just one question: there are two attributes given to `DW_TAG_GNU_template_template_param`, `DW_TAG_name` and `DW_TAG_template_name`. I see in the test you demonstrate printing the `DW_TAG_template_name` value, which is what this commit adds, but does the logical viewer print out the `DW_TAG_name` at any point?
