lrn@chromium.org a224db3a50 X64: Optimize access to external references. ... Access to an ExternalReference in non-serializable code will try to use an offset relative to the root-array register. Since the root-array is in the Heap object, and the Heap object is in the Isolate object, there's a good chance that any external data field is within a 32-bit offset of the root array register. It falls back on the original behavior if the serializer is enabled, if the root register isn't initialized or if the offset is not representable as a 32-bit value.
