abrown opened PR #2930 from shuffle-with-vperm to main:

When shuffling values from two different registers, the x64 lowering for
i8x16.shuffle must first shuffle each register separately and then OR
the results with SSE instructions. With VPERMI2B, available in
AVX512VL and AVX512VBMI, this can be done in a single instruction after
the shuffle mask has been moved into the destination register. This
change uses VPERMI2B for that case when the CPU supports it.
