[Paul Walker via Phabricator via llvm-commits]

+  def : SVE_2_Op_Imm_Pat_Zero<nxv16i8, op, nxv16i1, i32, SVEShiftImmL8, !cast<Pseudo>(NAME # _ZERO_B)>;
+  def : SVE_2_Op_Imm_Pat_Zero<nxv8i16, op, nxv8i1,  i32, SVEShiftImmL16, !cast<Pseudo>(NAME # _ZERO_H)>;
----------------
These operand types (plus the tvecshiftL ones above) are specific to left shifts.  You might want to take inspiration from `sve_int_shift_pred_bhsd`.
