All existing loader tests are switched to an integration test added with the new rule. Also, the getenv test is now enabled as an integration test. All loader tests have been moved to test/integration. Also, the simple checker library for the previous loader tests has been moved to a separate directory of its own. A follow up change will perform more cleanup of the loader CMake rules to eliminate now redundent options. Reviewed By: lntue, michaelrj Differential Revision: https://reviews.llvm.org/D122266
