add Westmere as a qemu cpu model (v2)
Version 1 of this patch was:
Message-Id: <1307041990-26194-11-git-send-email-ehabkost@redhat.com
http://marc.info/?l=qemu-devel&m=130704415919346
This version doesn't have the duplicate feature bits on extfeature_edx, though,
as they are being removed from the Intel models (as they are reserved bits on
Intel CPUs).
Version 1 patch description:
This patch adds Westmere as a qemu cpu model. The only
additional guest visible feature of a Westmere relative
to Nehalem is the inclusion of AES instructions. However
as other non-ABI visible modifications exist along with
fabrication changes, the CPUID data of the corresponding
deployed silicon was altered slightly to reflect this.
We've seen isolated cases where apparently unrelated yet
slightly incoherent CPUID data has caused problems, most
notably during guest boot. Providing Westmere as a
model separate fro Nehalem allows us to more easily address
such quirks.

Changes version 1 -> version 2:
- Remove the duplicate feature bits on extfeature_edx, that are
reserved on Intel CPUs
- Reorder feature flags
- Remove x2apic from the definition because x2apic requires some fixes
that have to be resubmitted
