Compiler crashes when a module is named Js

[shulhi]

It crashes with Not_found error.

To reproduce,

module Js = {
  let f = () => 1
}

let x = Js.f()

Playground,

Instead of crashing, we should probably throw a better error that a module can't be named Js or something (since we already have Js module).

Can't we...?

If I have a module named Map inside a module named A, doing open A will throw a warning that Map shadows the Map from Core. Maybe we should follow the same behavior?

Yes, I think so. And it should allow users to have their own Js bindings with/without opening Core in the future releases.
