I think this should be moved out of the if-block (but maybe needs its own vector
presence check instead?).

Hmm, I don't get it. If we have a TypeFeedbackInfo then it'll have a valid
feedback_vector in it, so what would moving it out of the if block help?

+    TypeFeedbackVector* vector = info->feedback_vector();
+    *ic_with_type_info_count += vector->ic_with_type_info_count();
+    *ic_generic_count += vector->ic_generic_count();
   }
   if (*ic_total_count > 0) {
     *type_info_percentage = 100 * *ic_with_type_info_count / *ic_total_count;
