The problem seems to be the tentative parsing in cp_parse_template_id, which
tries every crazy thing it can, and when nothing works, it just gives this
catch all diagnostic. 

But debugging the C++ parser is an absolute pain, I hope someone with more
patience takes a shot at this. The current diagnostic is just awful.
