Add flag which moves super initializer statement

Add flag which moves super initializer statement

--move_super directs the VM compiler to move the super initializer
of a constructor to the end of the initializer list. The default
value is false. If we opt to enable this functionality, the implicit
phase parameter of constructors can be eliminated, simplifying
constructors significantly.
