* Move FFI tests into a separate test suite. They never belonged in standalone_2/ since they are not only available in the standalone VM. Also, we want to have a separate status file. * Add new "SharedObjects" option to test files to copy needed shared objects to the Android device for testing. * Add support to compiler/runtime_configuration.dart for testing JIT-mode on Android. * Add new configurations and builders to test_matrix.json to test JIT-mode on Android. * Clean up status file entries for FFI (we didn't need to special-case stress & subtype tests).
