message:
  Bug#37516 DELETE using UNIQUE index deletes the wrong row
  
  Code for the read-before-write removal optimisation when using 
  unique indexes did not work correctly when the base table
  had no primary key (i.e. hidden primary key).

per-file comments:
  mysql-test/suite/ndb/r/ndb_hidden_pk.result
    New result file
  mysql-test/suite/ndb/t/ndb_hidden_pk.test
    Add testcase file for tables with hidden primary key, and some preliminary tests
  sql/ha_ndbcluster.cc
    Always use index for access if requested to, even if the table has a hidden primary
key.
