[pushed] c++: remove redundant testcase [PR83258]

[Patrick Palka via Gcc-patches]

I noticed only after the fact that the new testcase template/function2.C
(from r14-708-gc3afdb8ba8f183) is just a subset of ext/visibility/anon8.C,
so let's get rid of it.

gcc/testsuite/ChangeLog:

        * g++.dg/ext/visibility/anon8.C: Mention PR83258.
        * g++.dg/template/function2.C: Removed.
