Fix a typo causing inverted semantics when (even AVX2) code is compiled for AVX512 systems, e.g. via -march=native
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112443 where the changeset is from

It manifests in e.g. failing PyTorch tests where sgn/sign tests involving uint8_t are failing such as

  • test_reference_numerics_normal_sgn_cpu_uint8
  • test_reference_numerics_normal_sign_cpu_uint8
  • test_reference_numerics_small_sgn_cpu_uint8
  • test_reference_numerics_small_sign_cpu_uint8

This is summarized in the log as

@Flamefire For good measure, can you add some more info to the description of this PR in what context that this fixes a problem (I think it's mostly about failing PyTorch tests)? If possible, please add the relevant error messages too, so people searching for answers for the problem they're seeing will easily hit this PR...
