Johnny Chen bb6e9d8cf7 Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after calling 
ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2.
Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from
ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).
