Tail call optimisation was previously disabled on all targets other than iOS5.0+. This enables the tail call optimisation on all Thumb 2 capable platforms. The test adjustments are to remove the IR hint "tail" to function invocation. The tests were designed assuming that tail call optimisations would not kick in which no longer holds true. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203575 91177308-0d34-0410-b5e6-96231b3b80d8
