[RISCV] Fold (vslide1up undef, v, (extract_elt x, 0)) into (vslideup x, v, 1) (#154847)
To a slide1up, if the scalar value we're sliding in was extracted from
the first element of a vector, we can use a normal vslideup of 1 instead
with its passthru being that vector. This can eliminate an
extract_element instruction (i.e. vfmv.f.s, vmv.x.s).
