Because the default build configuration of the server will remain at -DWITH_INNODB_AHI=ON, we want to test the instrumentation. We make and revert the test adjustments in separate commits on purpose, so that this commit can be easily reverted later if the default build configuration is changed to -DWITH_INNODB_AHI=OFF.
