> Today we do two hash lookups, where in most cases a single one is enough. E.g. SR.getNumericDocValues
initializes the FieldInfo (first lookup in FieldInfos), however if that field was already
initialized, we can simply check dvFields.get(). This can be improved in all getXXXDocValues
as well as getDocsWithField.
