 * Removes all provided values from `array` using `SameValueZero` for equality

 *
 * **Notes:**
 *  - Unlike `_.without`, this method mutates `array`.
 *  - `SameValueZero` comparisons are like strict equality comparisons, e.g. `===`,
 *    except that `NaN` matches `NaN`. See the [ES spec](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-samevaluezero)
 *    for more details.
