They need to agree about when to delegate to CloneFastJSArray, since it produces arrays which are potentially COW. If they don't agree, TF generates code which produces a COW array and then expects it to be non-COW -> immediate deopt. This CL gets rid of the discrepancy in the case when there's exactly one argument and it's the number 0. Some corner cases remain, e.g., 1st argument not a number but ToInteger returns 0. These should be extremely rare in the real world.
