  -----------
  PR42513: Fix handling of function definitions lazily instantiated from
friends.

When determining whether a function has a template instantiation
pattern, look for other declarations of that function that were
instantiated from a friend function definition, rather than assuming
that checking for member specialization information on whichever
declaration name lookup found will be sufficient.
