I can commit changes partially.

- Add -fmodules-ignore-macro (llvm-config, libclang)

Their -DMACROs don't change headers' behavior. Just let them ignored.

- Unittests

They use -frtti. I thought they may be built w/o modules. Any better idea?

- DynamicLibraryTests

It doesn't use add_llvm_library(). Give -fno-modules with target_compile_options().

- libFuzzer

It doesn't depend on LLVM libraries. Just suppressing with -fno-modules.

- LLVMgold

  add_definitions( -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 )

It prevents reusing modules. I think they may be pruned since HandleLLVMOptions.cmake provides them conditionally.
