    [cleanup] Introduce a dedicated FeedbackCell. · aff1f378
    Benedikt Meurer authored
    This is preparatory cleanup work for eventually tracking the functions
    (rather than concrete closures) in the CALL_IC, also for builtins like
    the default PromiseCapability [[Resolve]] and [[Reject]] functions. It
    adds a new FeedbackCell type, which is used by JSFunctions consistently
    now to reference the feedback vector (or undefined if not the function
    is not compiled yet or is a native/asm.js function).
    
    This also changes the calling convention for FastNewClosure builtin and
    the JSCreateClosure operator in TurboFan to carry the FeedbackCell here
    instead of the parent FeedbackVector and the slot index. In addition we
    eliminate the now unused %InterpreterNewClosure runtime function.
