I think a single test file would better demonstrate the differences between how C and C++ global variables are interpreted.
I think you should just have different verify prefixes and two RUN lines. One for C and one for C++.
Then the `clang_analyzer_value` would demonstrate nicely if the global initializer expression was taken into account or not.
