All CPU features which QEMU does not know about but libvirt knows them
(currently "cmt" is the only one) are implicitly disabled by QEMU and
should be present in x86_64-cpuid-*-disabled.xml.

The new command can be used to generate test data for virCPUUpdateLive.
When "cpu-cpuid.py diff x86-cpuid-Something.json" is run, it reads raw
CPUID data stored in x86-cpuid-Something.xml and CPUID data from QEMU
stored in x86-cpuid-Something.json to produce two more CPUID files:
x86-cpuid-Something-enabled.xml and x86-cpuid-Something-disabled.xml.
- x86-cpuid-Something-enabled.xml will contain CPUID bits present in
x86-cpuid-Something.json (i.e., enabled by QEMU for the "host" CPU)
- x86-cpuid-Something-disabled.xml will contain all CPUID bits from
x86-cpuid-Something.xml which are not present in
x86-cpuid-Something.json (i.e., CPUID bits which the host CPU
supports, but QEMU does not enable them for the "host" CPU)

The new script is going to be more general and the original
functionality can be requested by "cpu-cpuid.py convert".
