Enable C++11 mode for iOS

Enable C++11 mode for iOS

Matches the flags to the OS X clang settings for C++11 to minimize
confusion, but it would be straightforward to enable the string literal
warning on iOS at this point.

Removes a warning suppression that's duplicated by an Xcode setting just
above (again, matching OS X)

How do we plan to be notified when we need to change this part of the
configuration? Should you modify the other TODO to have whoever changing the
other one also do the change here?

I'll check beck. I'd rather nobody change iOS compilation flags out from under
us, since it may require extra work.

thakis: FYI, finally turning on C++11 for iOS. When you guys change the mode,
let me know and I'll update to match!

Your code is likely broken or HEAD is junk. Please ensure your
code is not broken then alert the build sheriffs.
Look at the try server FAQ for more details.

Sigh. The SDK should be 6.1, but CQ at least has 6.0, which apparently has
different enum declaration. Will get that resolved and try again.
