LOG: [Templight] Don't display empty strings for names of unnamed template parameters
Patch originally by oktal3000: https://github.com/mikael-s-persson/templight/pull/40
When a template parameter is unnamed, the name of -templight-dump might return
an empty string. This is fine, they are unnamed after all, but it might be more
user friendly to at least describe what entity is unnamed.
