Could you please move the new function declarations and new code to

I would like to introduce this option later, it's used for fine tuning,
VLA vectorizer should be able to work without this tuning option.

So I think this was in a patch I already ACK'd from Juzhe.

+mriscv-vector-lmul=
+Target RejectNegative Joined Enum(riscv_vector_lmul) Var(riscv_vector_lmul) 
Init(RVV_LMUL1)
+-mriscv-vector-lmul=<lmul>     Set the vf using lmul in auto-vectorization.

Same question for this

Similarly.
