When delegating PF to VS, it should update vstval; when delegating PF to S, it should update stval; otherwise, it should update mtval. However, the previous NEMU sometimes updates vstval when delegating PF to VS. It's really strange that we did not find this bug brefore. This patch also adds INTR_TVAL2_REG / INTR_TINST_REG macro and uses them to refractor some other codes.
