Bug #22909 Using CREATE ... LIKE is possible to create
           field with invalid default value
Bug #35935 CREATE TABLE under LOCK TABLES ignores FLUSH
           TABLES WITH READ LOCK
Bug #37371 CREATE TABLE LIKE merge loses UNION parameter

fails, thinking it finds an existing table". This patch backports
test coverage missing in the original backport. The patch contains
no code changes.
