Do we want to point the parameter out with a caret, instead or at least in
addition to printing the decl name?
You can keep the main diagnostic pointing to the template location as
currently, but you could also forward the source range of the parameter to the
diagnostic, and this should make it so the parameter gets highlighted.
If the parameter is anonymous, as often happens, the diagnostic does not get
degraded.
