Issue:
prefer-destructuring should not check non-numeric indexes
**Tell us about your environment**

* **ESLint Version:** 4.14.0

**What parser (default, Babel-ESLint, etc.) are you using?** default

**What rule do you want to change?**  prefer-destructuring

**Does this change cause the rule to produce more or fewer warnings?**  Fewer

**How will the change be implemented? (New option, new default behavior, etc.)?** New default behavior

**Please provide some example code that this change will affect:**

```js
const INTEGER_WORDS = {
  one: 1,
  two: 2,
  three: 3,
  four: 4,
 };

let num = 1;
num = INTEGER_WORDS[num]; 
```

**What does the rule currently do for this code?**

Generates a warning for `num = INTEGER_WORDS[num];`

**What will the rule do after it's changed?**

It will ignore array indexes/keys that are not constants. I would argue this should **always** be the case, as it must be considered bad practice to destructure from a computed index or key.
