f67c2cd7 - [RISCV] Handle Zvabd and XRivosVizip EEWs in RISCVVLOptimizer (#184117)

[RISCV] Handle Zvabd and XRivosVizip EEWs in RISCVVLOptimizer (#184117) This allows the VL optimizer to handle more cases that RISCVVectorPeephole currently catches. The XRivosVizip instructions have ReadsPastVL=true, so only the vl of the zip instruction itself is reduced, not its inputs.
