+        [JSC] Generate put_by_val_direct for indexed identifiers instead of put_by_id with direct postfix
+        https://bugs.webkit.org/show_bug.cgi?id=145360
+
+        Reviewed by Darin Adler.
+
+        JSObject::putDirect only accepts non-indexed properties.
+        So when generating put_by_id (with direct postfix) for indexed property,
+        we should generate put_by_val_direct instead.
