In old days, Type::merge() had generated mangled name even for
TypeIdentifier.
It might be related to the topic.

Recently, a similar mangling definition issue around template instance had
reported, but finally it's marked as invalid.

  https://issues.dlang.org/show_bug.cgi?id=14592

Current dmd uses __U for the front-end only instances, but it won't appear
in the generated symbols.
It's just for the dmd-internal, so it's not documented in the spec.

I think we can take same approach.

As deadalnix pointed out, TypeIdentifier will never appear in any valid
symbol names in object files. Therefore the definition would be
dmd-internal specific, and can be removed from the spec.
