A "translation unit" is a sequence of tokens that are (only) lexically valid.

Looking at phase 8 (template instantiation), a "translated translation unit" is some
unspecified intermediate thing where all non-dependent constructs have been semantically
analyzed, but no templates have been instantiated yet. Maybe such a thing doesn't exist
in your implementation.
