Improvements: JIT article

[nawarian]

• Show Opcode sample
• Fix 1255 opcode.jit option and notify Benjamin about the issue so he can also fix it in his post
• Make it clear that language != environment and it is perfectly possible to compile Java or Python for example
• JavaScript is jitted too, make it clear. People got offended by this omission .-.

The 1255 issue on opcache.jit is about T - JIT trigger doesn't have a 5 value? Thanks for your great article.

Later on I found this option wasn't really wrong, is just that it wasn't documented yet. I'm still idle on how to update this article. Will do once I have further info.

Thanks for pinging me :D

Java is not an interpreted language but a compiled language ( AOT) Like C and C++.

Thanks for your great article :)
