LOG: [RISCV][TTI] Extract subvector at index zero is free (#81751)
Extracing a subvector at index zero corresponds to a type conversion and
possibly a subregister operation. We will not emit a vslidedown. As
such, they are free.
As an aside, it looks like we're not passing an index in for cases where
the subvec type is scalable. For at least index zero, we probably should
be.
