This is a repeat of commit r263989, which commit r264052 accidentally reverted.
Original commit message: The instruction set first appeared with Westmere, but not all processors in that and the next few generations have the instructions. According to Wikipedia[1], the first generation in which all SKUs have AES instructions are Skylake and Goldmont. I can't find any Skylake, Kabylake, Kabylake-R or Cannon Lake currently listed at https://ark.intel.com that says "IntelĀ® AES New Instructions" "No".
