[V8] SerializedScriptValue must be deserialized only once and in the right context
https://bugs.webkit.org/show_bug.cgi?id=36892
See also https://bugs.webkit.org/show_bug.cgi?id=34227 for the
corresponding JSC change.
General idea: SerializedScriptValue must be deserialized only once
and in the context of the intended MessageEvent recepient. The
approach we take for now is to eagerly deserialize when a
JavaScript wrapper for MessageEvent is created.
A better fix would be to keep a reference to the context in
MessageEvent and use it when lazily deserializing. It's harder to
do since the API doesn't have a clean method to have such a reference.
Tested by fast/dom/Window/window-postmessage-clone-frames.html. This
test still fails but only for the types which we can't serialize yet.
