This commit improves JitRunner so that it creates a target machine for the current CPU host which is used to properly initialize LLVM's TargetTransformInfo for such a target. This will enable optimizations such as vectorization in LLVM when using JitRunner. Please, note that, as part of this work, JITTargetMachineBuilder::detectHost() has been extended to include the host CPU name and sub-target features as part of the host CPU detection (https://reviews.llvm.org/D65760).
