In most cases, when running regression tests, you want to run them on the jdk image because that's the correct image and some tests will not work on other variants. However, many tests can be run successfully on the exploded image and since building the full jdk image takes quite a bit of extra time, especially when running a slowdebug build, enabling this as an option can significantly improve developer efficiency.

I therefor propose the new target "exploded-run-test". It will work just like run-test but it depends on and runs on the exploded image.
