             Bug #: 14094
           Summary: immediate in DecodeThumbAddSPImm has to left shift 2
                    bits
           Product: libraries
           Version: trunk
          Platform: PC

According to ARMv7 document in encoding T2 of SUB (SP minus immediate) section

imm32 = ZeroExtend(imm7:'00', 32);

so the parameter pass to MCOperand::CreateImm(imm) have to be "imm << 2"
