[libvirt] [PATCH v4 06/11] target-i386: Register properties for feature aliases manually
Instead of keeping the aliases inside the feature name arrays and
require parsing the strings, just register alias properties
manually. This simplifies the property registration code and will
simplify code that needs to look up property names for CPUID
bits.
