This patch adds a CPU definition for the Core Duo CPU. I tried to
resemble the original as closely as possible and document what features
are missing still. This patch enables the use of a recent CPU definition
on 32 bit platforms.
It also fixes two issues that went along the line:
- invalid xlevel in core2duo spec
While looking though the CPUIDs again, I found that xlevel is actually 8.
- non-PSE36 support
The CoreDuo CPUID does not expose the PSE36 capability, but CPUID
0x80000008 is tied to 36 bits. This broke Windows XP installation for
me, so I just set it to 32 bits width when PSE36 is not available. The
original CPU also exposes 32 bit width in CPUID 0x80000008.

the CPUID specification. This patch addresses this by specifying exactly
what is missing.
While going along the missing CPUID entries I also stumbled across
invalid and missing CPUID #defines while comparing them to the Intel
Documentation. This patch also addresses these. I found them too minor
to split them up in a separate patch.
Furthermore I looked through CPUID functions > 5 and realized that it
should be safe to bump the level to 10. I tried booting Linux with that
and it worked fine.

As noticed by Alexander Graf Atom is a name of a series with varying
features.

This patch adds a Core 2 Duo CPU to the available CPU types. The CPU
definition tries to resemble a real CPU as good as possible, whilst not
exposing features qemu does not implement.
The patch also includes some minor additions that Core 2 Duo CPUs have:
- New MSR: MSR_IA32_PERF_STATUS
- CPUID up to level 5 (cache info and mwait)

Right now CPU vendor identification contains a lot of magic numbers. The
patch cleans them up to defines, so we can identify the CPU later on
without copying magic numbers.

It helps debugging guests when yet unmapped pages are correctly reported
as, well, unmapped.

allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
and using the same definition in code translation code.
