Enables Machine Outlining for ARM and Thumb2 modes. This is the first patch of the series which adds all the basic logic for the support, and only handles tail-calls and thunks. The outliner can be turned on by using clang -moutline option or -mllvm -enable-machine-outliner one (like AArch64). Differential Revision: https://reviews.llvm.org/D76066
