of the abi we should be using. For targets that don't use the option there's no change, otherwise this allows external users to set the ABI via string and avoid some of the -backend-option pain in clang. Use this option to move the ABI for the ARM port from the Subtarget to the TargetMachine and update the testcases accordingly since it's no longer valid to set via -mattr. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224492 91177308-0d34-0410-b5e6-96231b3b80d8
