Debug Info: drop debug info via upgrading path if version number does not match. 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

Revert "Revert "DI: Fold constant arguments into a single MDString"" This reverts commit r218918, effectively reapplying r218914 after fixing an Ocaml bindings test and an Asan crash. The root cause of the latter was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a PR to investigate who requires the loose check (and why). Original commit message follows. -- This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a `\0` character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. llvm-svn: 219010
