        Depends on: 106891


This is a follow-up to the https://bugs.webkit.org/show_bug.cgi?id=106891 fix, which was not quite correct.

Now we do the array index check according to the ECMAScript 5, section 15.4:
"A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1."

Patch to follow.
