jacquesguan ba16e3c31f [RISCV] Decouple Zve* extensions and the V extension.
According to the spec, there are some difference between V and Zve64d. For example, the vmulh integer multiply variants that return the high word of the product (vmulh.vv, vmulh.vx, vmulhu.vv, vmulhu.vx, vmulhsu.vv, vmulhsu.vx) are not included for EEW=64 in Zve64*, but V extension does support these instructions. So we should decouple Zve* extensions and the V extension.
