The right approach, as I've said before, is simply not to *use*
for_each_template_parm.
It should be unncessary; the right approach should be to use
type_dependent_p and its friends.
That's not a trivial change, but it's the right change.
There might be a very few places where for_each_template_parm would
still be necessary -- but they will not be anything that should up on
the profile.
