Subject: [PATCH] Revert "x86" CPU model (not arch) back to "i386"

PR #13101 recently renamed the "i386" architecture to "x86", and it
seems the specific CPU model got swept up in that. "x86" is an umbrella
term that describes a family of CPUs, and the "i386" is the oldest
supported model under that umbrella.
