LIU Zhiwei 7d0d7338c2 target/riscv: add vector amo operations
Vector AMOs operate as if aq and rl bits were zero on each element
with regard to ordering relative to other instructions in the same hart.
Vector AMOs provide no ordering guarantee between element operations
in the same vector AMO instruction
