Tor Arne Vestbø 15bdf85f28 iOS: Bump max Xcode version to 4.6
We need to figure out where to draw the line when it comes to warning
about unknown compiler (Clang), Xcode, or SDK versions, but for now
building with Xcode 4.6 should not be an issue. We'll have to revisit
this and test with the full set of compiler/Xcode/SDKs we support
before the final release.
