[es2015] Simplify contract between parser and stub for derived constructors.

[es2015] Simplify contract between parser and stub for derived constructors.

this, and otherwise just return the value, and let the construct stub
builtin throw an exception if the result is a primitive instead of a
JSReceiver.
