Backport INFORMATION_SCHEMA.CHECK_CONSTRAINTS 

Implement according to standard SQL specification 2008.
The check_constraints table is used for fetching metadata about
the constraints defined for tables in all databases.

There were some result files which failed after running mtr.
These files are updated with newly create record with mtr --record.
