Reviewers: Toon Verwaest,
Description:
Object.observe: generate change records for indexed properties.
Details:
- Extend ElementAccessors with GetAttributes method.
- Add HasLocalElement, Get[Local]ElementAttribute methods to
JSReceiver/JSObject.
- Otherwise, mirror implementation for named properties.
Cannot correctly handle the cases yet where an accessor is redefined or
deleted.
