As per dotnet/runtime#78163 (comment), the fixes taken here are required for correctness.

These tests should effectively be ignored on Mono until the SIMD work is completed and IsHardwareAccelerated starts reporting true. The software fallbacks are not expected to be used in production scenarios and exist purely for validation purposes and to support scenarios like the debugger.

@naricc naricc closed this as completed Nov 30, 2022
