Instruction vmandnot and vmornot have been changed to vmandn and vmorn in Vector Extension Version 1.0

In RISC-V "V" Vector Extension Version 1.0 chapter 15.1, instruction vmandnot and vmornot have been changed to vmandn and vmorn. But in the riscv/arch_data/v_instructions.xml, the instructions are still the old version.

Are there any differences in the handcar implementation between the old and new versions, Or should I just change this xml file?
