LGTM, Awesome!! It seems a sign of the next big move for RISC-V vectorization!

OK. As it doesn't do anything and we'll be needing it anyway no harm
in adding it.

Hi, currently RVV vectorization only support picking LMUL according to
compile option --param=riscv-autovec-lmul= which is no ideal.
Compiler should be able to pick optimal LMUL/vectorization factor to
vectorize the loop according to the loop_vec_info and SSA-based register
pressure analysis.
Now
