add SandyBridge CPU model

This patches add the definition of a SandyBridge CPU model.

Summary of differences:

Flags present on actual hardware, but not on the added model definition:

- pbe, tm, ht, ss, acpi, vme, xTPR, tm2, eist, smx: host-specific
features, not exposed to guest....

add Opteron_G4 CPU model (v2)

This patch addes a Bulldozer-based Opteron_G4 CPU model.

This version has the ffxsr bit actually disabled, to match what was
documented below. Thanks to Andre Przywara for spotting the bug.

I am trying to be conservative with the new model, so I am enabling only...

cpu defs: remove replicated flags from Intel (v2)

This patch removes the replicated feature flags from cpuid 8000_0001:edx
(extfeature_edx) from Intel models, as the duplicated feature flags are present
only on AMD CPUs. On Intel models, only the i64, syscall, and xd flags are kept...

add Westmere as a qemu cpu model (v2)

Version 1 of this patch was:

Message-Id: <
http://marc.info/?l=qemu-devel&m=130704415919346

This version doesn't have the duplicate feature bits on extfeature_edx, though,...

cpu defs: uncomment empty extfeatures_ecx definition for Opteron_G1 (v2)

This should have no visible effect, but it should just clean up the
config file a bit.

This is based on a previous patch from John Cooper where this was introduced
with many other changes at the same time. Original John's patch submission is...

cpu defs: add pse36, mca, mtrr to AMD CPU definitions (v2)

This patch adds some missing flags to extfeature_edx, that were missing
according to AMD's latest CPUID document.

This is based on a previous patch from John Cooper where this was introduced
with many other changes at the same time. Original John's patch submission is...

cpu defs: use Intel flag names for Intel models (v2)

Use 'i64' instead of 'lm' and 'xd' instead of 'nx' on Intel models.

The flags have different names on Intel docs, so use those names for clarity.

This is based on a previous patch from John Cooper where this was introduced...

cpu models: reorder flag list to match bit order

This will make it easier to review and change the flag list in the future.

No behaviour change should be introduced by this, as it is just changing
the flag order on the config file.

To make sure the flag sets are really not changed by this patch, I have...

Add cpu model configuration support..

This is a reimplementation of prior versions which adds
the ability to define cpu models for contemporary processors.
The added models are likewise selected via -cpu <name>,
and are intended to displace the existing convention...
