Bug#11853126 RE-ENABLE CONCURRENT READS WHILE CREATING

             SECONDARY INDEX IN INNODB

This is a follow-up patch.

This patch moves part of the new test coverage to a test
file that is only run on debug builds since it used debug-
only features and therefore broke the test case on
release builds.
