Mainline (4.1.0) patch to test and fix this problem

The fix is trivial. The changes to the test case cause failures that are fixed
by the patch to ref_wrap_iterate.h. All of the tr1/3_function_objects tests
still pass on i686-pc-linux-gnu.

        * include/tr1/ref_wrap_iterate.h
        (reference_wrapper::operator()()): Don't dereferene the result of
        get() before calling it; it's already a reference.
        * testsuite/tr1/3_function_objects/reference_wrapper/invoke.cc:
        Test nullary calls to reference_wrappers.
