I also regard a comprehensive test suite as a very important part of this and following PRs, and probably we have one possible initial approach that is both easier to start with and has the benefit of preserving stability (and in ideal case certain compatibility with Khronos Translator). I mean DebugInfo section of Khronos Translator's test suite: https://github.com/KhronosGroup/SPIRV-LLVM-Translator/tree/main/test/DebugInfo

@bwlodarcz Would it be possible to take some tests from that test suite on this early stage of development of the extension? Do you see LIT tests cases from the Khronos Translator's test suite relevant to this initial PR?
