AESENCLAST      Perform the last round of an AES encryption flow
AESDEC      Perform one round of an AES decryption flow
AESDECLAST      Perform the last round of an AES decryption flow
AESKEYGENASSIST      Assist in AES round key generation

There are more of them. See the manual for all instructions that start with "AES".

There's another related group of instructions missing, AES Key Locker instructions. Search the manual for "AESKLE". The are:
