Feature Request

Is your feature request related to a problem? Please describe:

Relates to pingcap/tidb#10829

Describe the feature you'd like:

The parser should support MySQL's histogram syntax:

ANALYZE TABLE `t1` UPDATE HISTOGRAM ON `b` WITH 1024 BUCKETS;

Describe alternatives you've considered:

MySQL 8.0 compatibility

Teachability, Documentation, Adoption, Migration Strategy:

MySQL 8.0 compatibility (mysqldump in 8.0 will require this to be supported if information_schema.column_statistics is not empty).
