Description

When support for AVX512 EVEX encoded instructions was introduced in 8384, it created a single table for all instructions with an EVEX prefix. However, the EVEX prefix can be used in front of instructions with any of the major prefixes and two and three byte opcodes. This means that we really need to break this out on a per-instruction prefix basis just like we do with VEX encoded instructions.
