 I am being picky, but wouldn't be better  to have :
def int_aarch64_neon_vluti2_lane : DefaultAttrsIntrinsic<[llvm_anyvector_ty], [llvm_anyvector_ty, llvm_v8i8_ty,                                   llvm_i32_ty],  [IntrNoMem, ImmArg<ArgIndex<2>>]>;
def int_aarch64_neon_vluti2_laneq : DefaultAttrsIntrinsic<[llvm_anyvector_ty], [llvm_anyvector_ty, llvm_v16i8_ty,                                   llvm_i32_ty],  [IntrNoMem, ImmArg<ArgIndex<2>>]>;
It is just because I believe it is unusual to see the llvm.ir with 3 overloaded types.
