Backport of #90556 to release/8.0-staging

/cc @EgorBo

Customer Impact

Certain SIMD patterns may produce garbage values on CPUs with AVX-512 (mostly for unoptimized code). This is regression introduced in .NET 8 by AVX512 work.

There were two issues #96381 (customer reported) and #90508

Minimal repro:

doublecns=1.0;varvec=Vector128.Create(42.0)+Sse3.MoveAndDuplicate(Vector128.CreateScalarUnsafe(cns));Console.WriteLine(vec);

Prints <42, 43> while <42, 42> is expected.

Testing

A test is added

Risk

Low. It is a simple fix, and the problem reproduces only on machines with AVX512 and with very specific patterns in Tier 0.

Backport of #90556 to release/8.0-staging

/cc @EgorBo

Customer Impact

Certain SIMD patterns may produce garbage values on CPUs with AVX-512 (mostly for unoptimized code). This is regression introduced in .NET 8 by AVX512 work.

There were two issues #96381 (customer reported) and #90508

Minimal repro:

doublecns=1.0;varvec=Vector128.Create(42.0)+Sse3.MoveAndDuplicate(Vector128.CreateScalarUnsafe(cns));Console.WriteLine(vec);

Prints <42, 43> while <42, 42> is expected.

Testing

A test is added

Risk

Low. It is a simple fix, and the problem reproduces only on machines with AVX512 and with very specific patterns in Tier 0.
