Incorrect test data

[Lysias-1998]

The test data (in avx2neontestdata.h) of the following intrinsic are incorrect.

• MM512_CMP_PD_MASK
• MM256_CMP_PD
• MM256_CMP_PS
• MM512_CMP_PS_MASK I think it is because the interpretation of imm8 is inconsistent with the corresponding intrinsic of AVX. For example, in _mm512_cmp_pd_mask when when imm8=_CMP_EQ_UQ,

  typedef struct {
  float64_t a[8];
  float64_t b[8];
  __mmask8 expect[32];
  } test_mm512_cmp_pd_mask_data_model;
  static test_mm512_cmp_pd_mask_data_model g_test_mm512_cmp_pd_mask_data1 = {
  {-3.200000, 99.378500, 89.770000, 65.000000, NAN, -88.654000, NAN, 0.000000},
  {NAN, 15.600000, -6.200000, 2.000000, 41.200000, 14.000000, NAN, -88.654000},
  {...**81**...}
  };

  AvxToSve gives 81 whereas AVX gives 0, indicating that the comparing results of elements at index 0, 4, 6 are incorrect. And it is where the NAN sits.

The experiment is performed using Intel icx compiler and Intel sde (emulate tigerlake).
