[cleanup] Introduce a dedicated FeedbackCell. 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.
