Currently, in the TSBenchmark of call, ark is still not as good as v8. So it needs to be optimized. The way to set call frame is mainly optimized. After the optimization, fast path is executed when actual args is equal to declared args. Call type, numVregs, numArgs, native flag are all stored in one field for further stub.
