Doing this just like in riscv_vector::preferred_simd_modes
Others let Kito chime in more comments.
Thanks.

Ah, thanks for catching this. Yes, vector_mod

Wait for kito's final approval.

Hi,
this patch implements the autovec expanders for sign and zero extension
patterns as well as the accompanying truncations. In order to use them
additional mode_attr iterators as well as vectorizer hooks are required.
Using these hooks we can e.g. vectorize with VNx4QImode as base mode
and exte
