for-of loop variable scoping is invalid for nested loops

[simplan-niklas]

Describe the bug

If another loop (such as a basic for-loop or while-loop) is nested inside a for-of loop, the compiler doesn't recognize that the closure inside the inner loop closes over the outer loop variable.

Input code

for (const x of [0, 1, 2]) {
    for (let i = 0; i < 1; i++) {
        setTimeout(() => console.log(x));
    }
}

  "jsc": {
    "parser": {
      "syntax": "ecmascript",
      "jsx": false
