[clang] [llvm] [clang][Modules] Fixing Build Breaks When -DLLVM_ENABLE_MODULES=ON (PR #119473)

[Qiongsi Wu via llvm-commits]

https://github.com/qiongsiwu created https://github.com/llvm/llvm-project/pull/119473

A few recent changes are causing build breaks when `-DLLVM_ENABLE_MODULES=ON` (such as 834dfd23155351c9885eddf7b9664f7697326946 and 7dfdca1961aadc75ca397818bfb9bd32f1879248). 

This PR makes the required updates so that clang/llvm builds when `-DLLVM_ENABLE_MODULES=ON`.
