    [turbofan] Introduce Type for Class Constructors · b014d0ba
    Patrick Thier authored
    This CL splits the TF type for JSFunction into CallableFunction and
    ClassConstructor. This differentiation allows us to lower calls to the
    CallFunction Builtin only for functions that we can actually call.
    Class Constructors are special, as they are callable but should raise
    an exception if called.
    By not lowering class constructors to calls to CallFunction (but the
    more generall Call) builtin, we can remove the checks for class
    constructors from CallFunction (in a follow-up CL).
