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".

        * config/i386/i386.c (PTA_WESTMERE): Remove PTA_AES.
        (PTA_SKYLAKE): Add PTA_AES.
        (PTA_GOLDMONT): Likewise.
