Introduce the llvm.arm.hint(i32) intrinsic that can be used to inject hints into the instruction stream. This is particularly useful for generating IR from a compiler where the user may inject an intrinsic (e.g. __yield). These are then pattern substituted into the correct instruction which already existed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207242 91177308-0d34-0410-b5e6-96231b3b80d8
