Allows access to byte-element 2-register permutations(32-byte look up tables) and for 64-bit multi-shifts. Particularly adding this to accelerate the assembly of our `PERMUTE` opcode.
Uses the single-instruction AVX512 `vperm*` instructions to accelerate the `INT8_TYPE` and `INT16_TYPE` permutation opcodes. The `INT8_TYPE` is accelerated using `AVX512VBMI` subset of AVX512. Available since Icelake(Intel) and Zen4(AMD).
