ES6 class syntax should allow computed name method

Reviewed by Saam Barati.

Source/JavaScriptCore:

Added a new "attributes" attribute to op_put_getter_by_id, op_put_setter_by_id, op_put_getter_setter to specify
the property descriptor options so that we can use use op_put_setter_by_id and op_put_getter_setter to define
getters and setters for classes. Without this, getters and setters could erroneously override methods.
