Disable test, and use iOS simulator.
Disable test, and use iOS simulator.

I can't quite figure out why there is no diagnostic here
for the function being unavailable; this test is failing
the buildbots, and at this point I suspect the test is
wrong rather than the logic.  I'll investigate more with
my own iOS build of Swift.
