Close https://github.com/llvm/llvm-project/issues/64755 This wouldn't affect the form @import as the test shows. The two affected test case `diag-flags.cpp` and `diag-pragma.cpp` are old test cases in 2017 and 2018, when we're not so clear about the direction of modules. And the things that these 2 tests tested can be covered by clang modules naturally. So I change the them into clang modules to not block this patch.
