[InstCombine] Support negation of scalable-vector splats
This patch is an extension of D103421. It allows the InstCombiner to
generate the negated form of integer scalable-vector splats. It can
technically handle fixed-length vectors too but those are completely
covered by the preceding logic.
This enables extra combining opportunities for scalable vector types.
