JSDOMException is not reconciling it's weak stack trace

Reviewed by Yusuke Suzuki.
319782@main added .stack (and similar) properties to DOMException
objects. However, it failed to add a weak reference reconciliation
mechanism so the stack traces collected could be collected under the
instance. This patch adds a reconcileWeakReferencesAtGCEnd hook to
JSClientData, which forwards to the various ErrorInstance subclasses'
ISOSubspaces.
