https://github.com/dkolsen-pgi created https://github.com/llvm/llvm-project/pull/118389

Fix a compiler warning in `CIRGenConsumer::HandleTranslationUnit` in `clang/lib/CIR/FrontendAction/CIRGenAction.cpp`.  The warning was about a `default:` section in a switch statement that already covered all the values of an enum.  Delete the `default:` section.
