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

LIU Zhiwei 152934bade 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 887c29bc79 target/riscv: add vector index load and store instructions
Vector indexed operations add the contents of each element of the
vector offset operand specified by vs2 to the base effective address
to give the effective address of each element.

LIU Zhiwei c7a17d04a2 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.

LIU Zhiwei 9db3b70869 target/riscv: add vector configure instruction
vsetvl and vsetvli are two configure instructions for vl, vtype. TB flags
should update after configure instructions. The (ill, lmul, sew ) of vtype
and the bit of (VSTART == 0 && VL == VLMAX) will be placed within tb_flags.

Ian Jiang 5c3a2f391c riscv: Add helper to make NaN-boxing for FP register
The function that makes NaN-boxing when a 32-bit value is assigned
to a 64-bit FP register is split out to a helper gen_nanbox_fpr().
Then it is applied in translating of the FLW instruction.
