Changes:
- Use the pre-scanner to provide information for the parser about the existence of the class constructor
- The allocation of the super declarative environment is no longer needed
- The VM frame context holds the information about the this binding status
- Reduce the number of class related VM/CBC instructions
- Improve ecma_op_function_{construct, call} to properly set new.target
