Add a helper function getDebugInfoVersionFromModule to return the debug info version number for a module. "Verifier/module-flags-1.ll" checks for verification errors. It will seg fault when calling getDebugInfoVersionFromModule because of the incorrect format for module flags in the testing case. We make getModuleFlagsMetadata more robust by checking for error conditions. PR17982 llvm-svn: 196158
