target-i386/cpu: Introduce FeatureWord typedefs
This introduces a FeatureWord enum, FeatureWordInfo struct (with generation information about a feature word), and a FeatureWordArray typedef, and changes add_flagname_to_bitmaps() code and cpu_x86_parse_featurestr() to use the new typedefs instead of separate variables for each feature word. This will help us keep the code at kvm_check_features_against_host(), cpu_x86_parse_featurestr() and add_flagname_to_bitmaps() sane while adding new feature name arrays.
