This removes most of the pre-CommentStore text columns, and the $wgCommentTableSchemaMigrationStage setting that used to determine whether the columns were used. rev_comment remains in the code, as on Wikimedia wikis the revision table is too large to alter at this time. A future change will combine that with the removal of rev_user_text, rev_content_model, and rev_content_format (and the addition of rev_comment_id and rev_actor). CommentStore's constructor continues to take a $stage parameter, and continues to have the logic for handling it, for the benefit of extensions that might need their own migration process.
