<pre>Example test case:
=====
var x = 'y',
valueSet,
obj = {
get [x] () { return 1 },
set [x] (value) { valueSet = value }
};
obj.y = 'foo';
return obj.y === 1 && valueSet === 'foo';
=====
This will probably require three new opcodes: op_put_getter_by_val, op_put_setter_by_val, op_put_getter_setter_by_val.
Like the equivalent by_id opcodes, these opcodes will mostly be a clone of get_by_val and put_by_val, with slightly different behavior for being getters and setters, and for not consulting the prototype chain.</pre>
