Auto fix for rule "first"

[fnknzzz]

I would like to work on the rule first auto fixer. The small and controllable problem should be auto fixed. If can be merged, I may start working now. The strategy is put the no-first import declarations into the bottom of the first import declarations.

That sounds fine, as long as the following criteria apply:

1. imports are never re-ordered relative to each other, even if absolute-first is set.
2. if an import creates an identifier, and that identifier is referenced at module level before the import itself, that must also not be re-ordered.

About the second point.
const foo = bar; import bar from './bar.js';
This won't be re-ordered?

@fengkfengk correct, because that code will currently throw a TDZ error, and that error should be maintained by the autofixer.
