Hi Marcus,

In case this is still relevant - format strings are stored in TableGen files.

For example:
include/clang/Basic/DiagnosticLexKinds.td

…
def warn_header_guard : Warning<
  "%0 is used as a header guard here, followed by #define of a different macro">,
  InGroup<DiagGroup<"header-guard">>;
…

Hope this helps.
