Luajit should add arm64 support

I think it is acceptable to just skip the compilation step if no better solution is possible.
One the other side,if without compilation,the security may become a problem.

Hi folks, FYI luajit 2.1 supports arm64 now

Hello,I wanna to know that is the cocos2dx-lua 3.9 upgrade luajit to support iOS arm64?
Because if I run my app on iPhone 5s/6/6s, it cause a error of “module of ‘bit’ not found”, and the bit operation is contain in luajit but not in native lua.

i also find android arm64 module of ‘bit’ not found how to fix?
