This started to be rejected with r13-4035
c++: only declare satisfied friends
A friend declaration can only have constraints if it is defined. If
multiple instantiations of a class template define the same friend function
signature, it's an error, but that shouldn't happen if it's constrained to
only be declared in one instantiation.
Currently we don't mangle requirements, so the foos all mangle the same and
actually instantiating #1 will break, but for now we can test that they're
considered distinct.
gcc/cp/ChangeLog:
* pt.cc (tsubst_friend_function): Check satisfaction.
