Comment #9 on issue 4317 by [email protected]: @@isConcatSpreadable is
ignored by Array.prototype.concat when the arguments are arrays

Some Octane scores with and without the change. I haven't crunched the
numbers yet, but it can't hurt to store them here. It looks like there's no
real performance difference. First, here are the results without the
builtin (with that patch):
