Add parsing support for the `AS row_alias[(col_alias, ...)]` clause in INSERT ... VALUES and INSERT ... SET statements, as introduced in MySQL 8.0.19 (WL #6312) and required since VALUES() was deprecated in MySQL 8.0.20. Examples: INSERT INTO t VALUES (1,2) AS new ON DUPLICATE KEY UPDATE b = new.b; INSERT INTO t VALUES (1,2) AS new(m,n) ON DUPLICATE KEY UPDATE b = m; INSERT INTO t SET a=1,b=2 AS new ON DUPLICATE KEY UPDATE b = new.a; This is a parser-only change; planner/executor support for resolving the alias references is not included. The INSERT ... SELECT form of the row alias is not yet supported. Replays pingcap/tidb#67920. Refs sqlc-dev#22. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
REPLACE does not support the AS row_alias syntax in MySQL. Since ReplaceIntoStmt reuses InsertValues, add a check to reject any row alias parsed via that shared grammar rule. Replays pingcap/tidb#67920. Refs sqlc-dev#22. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Replays pingcap/tidb#67920 into marino. Partial fix for #22.

INSERT ... SELECT ... AS newform from #22. Adding it requires extending the fourSelect-branched alternatives ofInsertValuesand may introduce grammar ambiguity withSELECT's ownAStable alias — left for a separate PR.
