Testing macro for BIF

[RyanSiu1995]

I think we can trim the testing code with a macro for calling the bif function. During my development, the following codes were repeatedly entered.

let vm = vm::Machine::new();
let module: *const module::Module = std::ptr::null();
let process = process::allocate(&vm.state, module).wrap();
let args = vec![xxxxxxx];
let res = bif_the_function_I_want_to_test(&vm, &process, &args);

Most of the codes are not used for testing. The code duplication is so high that I think it can be replaced by a macro as a high order function like the following one.

macro_rules! test_it(func: func ; $($arg: expr), *) => {
  // The code as the above
}

I can do this in Elixir but not sure if it is valid in Rust. Does it sound a valid solution to you? @archseer If it is okay, I will do it and refactor the unit tests.
