When a base+displacement kind of operand is given in an index-mode instruction, the assembler does not flag it as an invalid instruction causing the user to get an incorrect encoding of that instruction leading to incorrect execution of the program. Enable assembler to recognize valid and invalid operands used in index mode instructions by classifying SOREG type into two further types XOREG (used uniquely in index addressing mode instructions) and SOREG for instructions working on base+displacement operands. Also cleaned up usage of obj.Addr.Scale on PPC64.
