  -----------
  [RISCV] Remove vp.reverse mask check in performVP_REVERSECombine (#180724)

Similar to #180706, the masked off lanes in vp.reverse are poison so can
be replaced with anything. Because of this, we should be able to fold a
masked vp.reverse(vp.load) into a vp.strided.load stride=-1 even when
the mask isn't all ones.
