Landed an ios-simulator baseline for this test in <http://trac.webkit.org/projects/webkit/changeset/196884> to get the bots back to green.

I believe this is the same issue as Bug 152448. It is because Intl.NumberFormat uses POSIX locale. The current proposed patch should fix it.

[Sukolsak Sakshuwong]

One way to reproduce this case:

$ LANG=en_US.UTF-8 ./jsc -e "print(Infinity.toLocaleString())"
∞
$ LANG=en_US_POSIX.UTF-8 ./jsc -e "print(Infinity.toLocaleString())"
INF

This issue has been fixed by https://trac.webkit.org/changeset/197261 Infinity.toLocaleString() now returns "∞" as it should.
