Core 2 Duo specification (Alexander Graf).

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)
