We turn a JSCallFunction node for f.apply(receiver, arguments) into a JSCallForwardVarargs node, when the arguments refers to the arguments of the outermost optimized code object, i.e. not an inlined arguments, and the apply method refers to Function.prototype.apply, and there's no other user of arguments except in frame states. We also replace the arguments node in the graph with a marker for the Deoptimizer similar to Crankshaft to make sure we don't materialize unused arguments just for the sake of deoptimization. We plan to replace this with a saner EscapeAnalysis based solution soon.
