Bug#12664445 - SYS_VARS.ALL_VARS: WRONG RESULTS RECORDED IN RESULT FILE - TEST CASES MISSING! 
      
The bug had missing test cases for three system variables. 
Test cases have been added for these variables:
'INNODB_FILE_FORMAT_MAX' 
'INNODB_ROLLBACK_SEGMENTS'
'INNODB_STATS_METHOD'
      
The 'sys_vars.all_vars' result file now looks like this:
      
select variable_name as `There should be *no* variables listed below:` from t2
left join t1 on variable_name=test_name where test_name is null;
There should be *no* variables listed below:
      
INNODB_LARGE_PREFIX
INNODB_LARGE_PREFIX
      
The variable 'INNODB_LARGE_PREFIX' is a newly added variable for MySQL 5.6.3 and the test will be added later by the developer.
