CodeGenCXX: Test that linetables work with variadic virtual thunks Add a frontend test for PR22929, which was fixed by LLVM r232449. Besides the crash test, check that the `!dbg` attachment is sane since its presence was the trigger. llvm-svn: 232450

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121
