target-i386: Add "feature-words" property to X86CPU
This property will be useful for libvirt, as libvirt already has logic
based on low-level feature bits (not feature names), so it will be
really easy to convert the current libvirt logic to something using the
"feature-words" property.
The property will have two main use cases:
- Checking host capabilities, by checking the features of the "host"
CPU model
- Checking which features are enabled on each CPU model
Example output:
$ ./QMP/qmp --path=/tmp/m \
qom-get --path=/machine/icc-bridge/icc/child[0] \
--property=feature-words
