luajit ios arm64 编译bytecode
纠正：quick2.2.6的lua5.1.5字节码可以只用一套字节码，虽然不知道是怎么回事，感觉是强制在64位的机器上用32位的字节码。
而这个32 64都可以用的分支我在lua官网查看，并没有找到。不知道这个是否是cocos官方修改的。
1.先做一个比对 lua luajit 32 64 bytecode 执行结果
测试代码
AppEntry.lua
print("Hello Lua Compile")Version.lua
print("luaversion", _VERSION)
local jit = require("jit")
print("jitversion", jit.version_num)lua32 lua64 luajit32 luajit64 是用相对应的lua,luajit编译的bytecode

2.测试版本 luajit2.1beta

先前luajit arm64编译都是在手机上编译然后上传到服务器上的，最近发现不在手机上也能编译，就是要开启LUAJIT_ENABLE_GC64
我在lj_arch.h 加入这个
#define LUAJIT_ENABLE_GC64然后在mac上同样编译出ios arm64能运行的bytecode。 总结：
1.各版本bytecode是不能互用的，如果又想支持armv7 arm64 的话 就是必须用两套bytecode。
2.如果只想用一套代码。就不要编译bytecode。
