    c++: Fix cp_build_function_call_vec [PR 98626]

    I misunderstood the cp_build_function_call_vec API, thinking a NULL
    vector was an acceptable way of passing no arguments.  You need to
    pass a vector of no elements.

            gcc/cp/
            * module.cc (module_add_import_initializers):  Pass a
            zero-element argument vector.
