Test cxx11_tensor_expr fails on AArch64 (armv8.1-a) with Neon

The test cxx11_tensor_expr fails on AArch64 (armv8.1-a):

Initializing random number generator with seed 1593792769

    actual   = nan
    expected = 0

Test test_minmax_nan_propagation() failed in ../unsupported/test/cxx11_tensor_expr.cpp (323)

Minimal reproducible example:

Eigen::Tensor<float, 1> vec_nan(10), vec_zero(10), vec_res(10);
const float qnan = std::numeric_limits<float>::quiet_NaN();
vec_nan.setConstant(qnan);
vec_zero.setZero();
vec_res.setZero();

vec_res = vec_zero.cwiseMax(qnan); // Should be 0 but is 8xNaN and 2x0

If vectorization is disabled this works as expected (that's most likely the reason the remainder of two float32x4_t packets is correct but the packets themself are not).
