+
+    [bindings] Use v8::Array::Iterate for converting script wrappables
+    
+    
+    This changes CreateIDLSequenceFromV8Array to use the new
+    v8::Array::Iterate() operation.
+    This speeds up the "execBundles" part of the microbenchmark
+    at crbug.com/dawn/1858 by around 3x.
+    This depends on crrev.com/c/4846594 landing (and rolling) first.
+    
+    This is a slight re-work of https://crrev.com/c/4847447/3,
+    originally by jkummerow@chromium.org
+
