The ARM64 has VREV16/VREV32/VREV64 permute operations that are used in the wild. It will be nice to add them to the AnalyzeShuffle and generate single instruction for ARM64 (and somewhat efficient code for x86)

This seems like it doesn't need to make the train for FF90, so lowering priority.
Severity: S2 → N/A

There was a win at reverseInt16x8 about 8% on my local benchmark on a x64 machine.

On ARM64 platform, the local benchmark test 1-2% win for all added reverse ops.
