Commutes the operands in the given instruction by changing the operands order and/or changing the instruction's opcode and/or the immediate value operand.
The arguments 'CommuteOpIdx1' and 'CommuteOpIdx2' specify the operands to be commuted.
Do not call this method for a non-commutable instruction or non-commutable operands. Even though the instruction is commutable, the method may still fail to commute the operands, null pointer is returned in such cases.
