Eduardo Habkost - Dec. 28, 2012, 8:34 p.m.
Note that this is temporary: just like we would eventually kill usage of
x86_def_t inside cpu_x86_parse_featurestr(), we will eventually kill
usage of X86CPU inside that function as well.

This will help us keep the x86_def_t usage restricted to the CPU object
creation code.
