+       return a value with a memory address.
+       (eval_call): For calls to GNU ifunc functions, try to find the
+       type of the target function from the type that the resolver
+       returns.

+       (call_function_by_hand_dummy): Adjust to use the function type
+       returned by find_function_addr.
+       (find_function_addr): Add 'function_type' parameter and move
