Does has_only_simple_this_property_assignments imply
has_only_this_property_assignments?  If it does you can remove the first line
here.

-      fun->shared()->this_property_assignments_count() > 0) {
+      fun->shared()->this_property_assignments_count() > 0 &&
+      fun->shared()->has_only_simple_this_property_assignments()) {
     int count = fun->shared()->this_property_assignments_count();
     if (count > in_object_properties) {
       count = in_object_properties;
