Mathias Bynens 35b6aa3849 [js] Remove CHECK_OBJECT_COERCIBLE for Array methods ... The spec got rid of `CheckObjectCoercible` a while back, and so should we. This change is not observable in most of the affected cases since `ToObject` is up near the top of most Array method algorithms. An example of an observable effect of this change occurs for the following input: Array.prototype.sort.call(null, 1); Behavior before applying the patch (incorrect message): TypeError: Array.prototype.sort called on null or undefined Expected behavior: TypeError: The comparison function must be either a function or undefined This patch removes `CheckObjectCoercible` and adds tests to ensure the few observable cases are addressed correctly. The patch also adds a missing `ToObject(this)` to `Array.prototype.lastIndexOf` which would otherwise become observable as a result of `CheckObjectCoercible` being removed.
