Code coverage does not work with GHUNIT_AUTOEXIT

[dodikk]

Steps :

1. Set up coverage flags as described in https://github.com/farcaller/ios-tdd/tree/master/Coverage
2. Apply the flush() patch https://github.com/leroymattingly/XCode5gcovPatch
3. Set ghunit environment as shown below and run the application

    setenv("GHUNIT_AUTORUN" , "YES", 1);
    setenv("WRITE_JUNIT_XML", "YES", 1);
    setenv("GHUNIT_AUTOEXIT", "YES", 1);

Acutal result :

Coverage files not generated (CoverStory.app shows nothing)

Expected result :

Coverage files generated successfully in the "build intermediates" directory

When disabling GHUNIT_AUTOEXIT flag and closing the simulator using the "home button" coverage files are generated just fine

The patch uses a UIApplicationDidEnterBackgroundNotification notification. https://github.com/leroymattingly/XCode5gcovPatch/blob/master/UIApplication%2BGCovFlush.m

Either the notification should be fired or __gcov_flush() should be invoked on GHUNIT_AUTOEXIT condition.
Implementation approach : https://github.com/pivotal/cedar/search?q=gcov&ref=cmdform
