Port: 1cd7a582 Original Commit Message: Class Constructors are special, because they are callable but [[Call]] raises an exception. Instead of checking if a JS function is a class constructor for every JS function call, this CL adds a new instance type for class constructors. This way we can use a fast instance type range check for the common case, and only check for class constructors in the uncommon case were a class constructor is called and when we need to raise an exception.
