Currently the `hip-not-supported.hip` is the equivalent lit test for this. Because we don't have a functionality of checking the module as of now, it also depends on execution. I also wanted to have some proper checks in between whole parser flow, So i was planning later we can add a/several dump option/s in clang-repl and test all the steps rather than just the flow.
