LLVM is struggling to optimize this test when AVX is enabled, but
there's not much Rust can be expected to do about it. Let's ignore that
part until we learn more on the LLVM side, hopefully fixed and updated.

I was also disabling this particular array length in https://github.com./rust-lang/rust/pull/139430/files#diff-a6f7809c5adbbdcc5080d91b5615b2d7ec2e69a5df97470dd3d7d13a9a90cab0R16 while keeping the test for that CPU with a different length that's easier to optimize (by being a multiple of the vector size), so accepting that PR would be another way to accomplish this goal.
