QNO/QE : switch to another Queue if source register is Not Odd (Even)

The processor will change the CQ register if the source register's LSB (in SRC1) is not set (the value is even).

The current queue is then given by the 2-bit field located in SRC2.

The Imm16 field is not used because the negation field already provides with a XOR.

This instuction is also known under the alias QE.
