rG2c4e38fa6f33: [X86] Emit REX prefix immediately before the opcode
Summary

Fix prefix emission order to emit REX immediately before the opcode (SDM vol2,
2.1, Figure 2-1). According to SDM vol2 2.2.1, "Other placements are ignored".

This fix has a side effect of outputting segment override prefix in a different
order than previously (benign).
