* Compress/expand (these replaces what is typically some awkward move mask, big table, permute combination and is super-useful to have, and saves like ~1k-4k [sometimes more] of tables you otherwise keep warm in L1D for no good reason)
* Disp8*N encoding (purely a code size thing; this alone does a very good job at offseting the extra cost of EVEX)
* Variable shifts on not just DWords/QWords, but also words. (THANK YOU))
