Update upstream bots to target iOS SDK 9.0.

Update upstream bots to target iOS SDK 9.0.

Xcode 7.0 has been publicly released and iOS downstream requires it to build
so use the iOS 9.0 SDK with Xcode 7.0 for the bots upstream.

Run the tests on all the currently supported iOS version 7.1, 8.3 and 9.0.

PTAL

Time difference. It was like 5am for me and 8am when you re-sent. (:

Lgtm.

Gonna CQ in a sec. I'm just checking the non-CQ iOS try bots (they use Xcode
instead of ninja, which matches main).

Sorry, the resend was just for adding justincohen@ as a second reviewer, not
because I thought you were too slow, but because I wanted his input on running
tests on iOS 7, 8 and 9. My goal was not to pressure you into quicker review,
I'm well aware that you are in a different timezone.

I'm sorry that you felt it as such. I should have been clearer when adding
justincohen@ as a secondary reviewer, and instead of just PTAL, I should have
written something like "justincohen@ do you think it is a good idea to run the
tests on all supported iOS versions or should I just run then on the two most
recents one".

I'll try to do better, and again, thank you for your amazing job!

No, no. I was just kidding.
