+        [JSC] Make ArithClz32 work with Cell arguments
+        https://bugs.webkit.org/show_bug.cgi?id=161369
+
+        Reviewed by Geoffrey Garen.
+
+        ArithClz32 was already working with all primitive types
+        thanks to the magic of ValueToInt32.
+        This patch adds support for cell arguments through a function
+        call.
