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. PR target/104967 gcc/ChangeLog: * config/rs6000/rs6000-c.cc (find_instance): Skip instances with null function types.
