fix alpha cmovxx instruction
The CMOV instruction is defined by the alpha manual as: CMOVxx Ra.rq,Rb.rq,Rc.wq !Operate format CMOVxx Ra.rq,#b.ib,Rc.wq !Operate format Operation: IF TEST(Rav, Condition_based_on_Opcode) THEN Rc ← Rbv The current qemu behavior inverses Ra and Rb. This is fixed by this patch.
