    c++: non-templated friends [PR105852]

    The previous patch for 105852 avoids copying DECL_TEMPLATE_INFO from a
    non-templated friend, but it really shouldn't have it in the first plac=
e.

            PR c++/105852

            check to an assert.

            on non-templated friends.
            (tsubst_friend_function): Adjust.

    gcc/testsuite/ChangeLog:
