LIU Zhiwei	268fcca66b	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.

LIU Zhiwei	022b4ecf77	target/riscv: add fault-only-first unit stride load ... The unit-stride fault-only-fault load instructions are used to vectorize loops with data-dependent exit conditions(while loops). These instructions execute as a regular load except that they will only take a trap on element 0.

LIU Zhiwei	751538d5da	target/riscv: add vector stride load and store instructions ... Vector strided operations access the first memory element at the base address, and then access subsequent elements at address increments given by the byte offset contained in the x register specified by rs2. Vector unit-stride operations access elements stored contiguously in memory starting from the base effective address. It can been seen as a special case of strided operations.
