    rs6000: Skip overload instances with NULL fntype [PR104967]

    For some overload built-in function instance, if it requires
    a data type which isn't defined on the target, its fntype
    would be initialized as NULL.  This patch is to consider
    this possibility in function find_instance, as shown in
    PR104967.

    gcc/ChangeLog:

            * config/rs6000/rs6000-c.cc (find_instance): Skip instances with
null
            function types.
