bug report

When I read the llvm sources, l find a problem as follows. There seems to be a mistake in this (Arm::Addrsi) instruction’s Operands.

In llvm version 7.1 , lib/Target/ARM/ARMISelDAGToDAG.cpp : 2696 - 2698. The latest version is also so.

SDValue Ops[] = { V, V, Reg0, ShImmOp, getAL(CurDAG, dl), Reg0,
                  Reg0 };
CurDAG->SelectNodeTo(N, ARM::ADDrsi, MVT::i32, Ops);

I think  that the third arg should be removed.
