this needs to also be `DefaultAttrsIntrinsic<[LLVMVectorElementType<0>],
[llvm_anyfloat_ty]>;` like you have it on `int_dx_length`. `LLVMMatchType<0>`
will match `llvm_anyfloat_ty` which means it will make the expected return be a
vector when length returns are scalars. Also if you don't use
`DefaultAttrsIntrinsic` you won't get all the default behaviors of intrinsics.
