`REQUIRES: clang` only affects whether the LIT test is run or not.  The `clang` keyword, in this case, has to be present in `config.available_features` for the test to run.  Since we do not add `clang` into the available features list, the test will just not run.  Even if we did enabled `clang` as a LIT feature, we still have to guarantee that the `clang` target (that builds the actual `clang` executable) is built before the test runs - this can only be done by setting proper dependency in CMake files.

If building the whole `clang` under `check-flang` is not acceptable, we need another solution.
