> These were

> > Original commit message from r217995:
> >
> > Instantiate exception specifications when instantiating function types
> (other
> > than the type of a function declaration). We previously didn't
> instantiate
> > these at all! This also covers the pathological case where the only
> mention of
> > a parameter pack is within the exception specification; this gives us a
> second
> > way (other than alias templates) to reach the horrible state where a type
> > contains an unexpanded pack, but its canonical type does not.
