Hi Jackson,

JSX files have a different extension, right? Why don't we make it a 
separate major mode?

It can also live in js.el and derive from js-mode. The only thing it'll 
change (for now?) is the indentation function.

And for those who also want the js2-mode AST, we can either tell them to 
use js2-minor-mode, or also create a js2-jsx-mode that would derive from 
js2-mode and use the indentation function defined here.

Then there will be no need for the option js-indent-jsx.
