Add additional debug job with Clang
We now support Clang which emits more warnings than GCC. This should be reflected in the testing.
- Have two testing images, one with Clang and one with GCC.
- Compile a smaller executable for debug builds.
- Have two debug builds, one with GCC and one with Clang.
- Fix all compiler warnings
How to test the implementation?
- Both Debug builds succeed (without warnings)
