Because of its dependency on clang (and potentially other compilers downstream, such as swift) lldb_private::GetVersion already lives in its own library called lldbBase. Despite that, its implementation was spread across unrelated files. This patch improves things by introducing a Version library with its own directory, header and implementation file. The benefits of this patch include: - We can get rid of the ugly quoting macros. - Other parts of LLDB can read the version number from lldb/Version/Version.inc. - The implementation can be swapped out for tools like lldb-server than don't need to depend on clang at all.
