Object.getOwnPropertySymbols ( O )
1. Return ? GetOwnPropertyKeys(O, Symbol).
GetOwnPropertyKeys ( O, type )
1. Let obj be ? ToObject(O).
2. Let keys be ? obj.[[OwnPropertyKeys]]().

4. For each own property key P of O that is a Symbol, in ascending
chronological order of property creation, do
a. Add P as the last element of keys.
5. Return keys.
