trace_processor: extract StorageSchema::Column and remove ColumnReporter Following on from extracing all the column implementations from StorageSchema, this CL also extracts out the column itself. This allows cool stuff to happen without circular header dependenices involving StorageSchema. Also remove the concept of StorageCursor::ColumnReporter which never had any implementors other than StorageSchema::Column and added a lot of overhead for creating vectors of columns on every Filter operation. This improves performance for JOINs involving nested subqueries Old code on a 6MB trace: 90ms New code on a 6MB trace: 60ms Change-Id: I5ad080dbc3d419dd9aeb5d7fb011233c108695d9
