REX: Set REX bits in accordance with 32-register environment REX.RXB bits were set for high-8 registers previously. Since high-16 zmm registers are newly added, those bits should be set as one bit of binary number of register value. Similarly EVEX.R'/V'/X should be set in the same manner. Authored-by: H.
