The only place this enum is stored is bit-field I annotate in this patch. Like it was with `TypeAlignment`, I'm only encoding status quo that actual underlying type for this enum is unsigned. There is no impact on memory footprint, because I'm yet to see us deriving bit-field width from underlying type of enum.
