Remove CPU_ prefix from x86 cpu_feature_level_t enum options

Browse source 
This makes the option names of cpu_feature_level_t consistent
and it also makes it easier to list options of the cpu_feature_t
enum just by their prefix (because it now doesn't collide with
the prefix of cpu_feature_level_t options).
