    Description

      On behalf of: zifeihan (caogui@iscas.ac.cn)

      Currently ReductionV instructions in c2 for Vector API are not implemented in RISC-V.
      We'd like to support AndReductionV/OrReductionV/XorReductionV for RISC-V. The patches will be implemented by referring to aarch64 sve and riscv-v-spec v1.0 [1].
