I guess what I was trying to say was that I could not find a way to handle the 
new ARM intrinsic in SelectionDAGBuilder::visitTargetIntrinsic easily with the 
existing code so I had to introduce a case just for the ARM intrinsic in 
SelectionDAGBuilder::visitIntrinsic, and I am not sure if that is acceptable.
