Now we perform the correct check: making sure that we have TBI on for iOS7.0-Earlier and on for iOS8.0+Later. The actual functionality that occurs is that we /always/ have TBI on when the triple is an AArch64 target. Then the backend determines via the triple whether it is supported or not for the specific os version. I also removed the executable test bit requires since this test does not execute anything, it just runs FileCheck tests.
