It should be possible to post (clone) built-in JS objects to Workers

Reviewed by Gavin Barraclough.

Implement object cloning semantics for postMessage. Currently only
a partial implementation of the spec -- cloning of File, FileList,
ImageData, and RegExp were left out as they would have significantly
increased patch size.

Cloning requires multiple tree walks so we use a templated tree
walk function, allowing us to share a single implementation for
serialization, deserialization, and eventual destruction of the
serialized object tree.

Test: fast/dom/Window/window-postmessage-clone.html
