JSC support the ECMA-262 defined toUint32 conversion correctly (see ES5.1 section 9.6).  If WebIDL wants a different conversion, this is probably best supported in a wrapper function in WebCore/bindings, rather than in JSC.

This can be implemented in terms of JSValue::toNumber (as the WebIDL spec calls for), optionally optimizing access to integers using JSValue::isInt32 & JSValue::asInt32.

This bug should probably be retitled – JSC's toUint32 matches that of the appropriate spec.
