Support intrinsic functions `call`, `caller`, `bind`, `compile`

caller has been implemented successfully. but it's hard to implement call, bind and compile on this interpreter, because it compiles the whole program into one code block containing all the bytecodes that will be used later.
but compile destory the basic function of the whole compiling process and the framework of virtual machine. so if want to support these 3 functions, we must refactor the whole parse => codegen process and the virtual machine, especially changing the way of storing bytecodes and the way of binding them to functions.
