On Windows with LLVM/Clang `16.0.0-rc2` tag I can't build clang due to the fact that the `HAVE_CLANG_REPL_SUPPORT` is being set to `ON` due to how the CMake code is being written.
Visual C++ will fail to link `clang-repl.exe` due to the big number of symbols.
The following code allows me to build by setting the `HAVE_CLANG_REPL_SUPPORT` to `OFF` when configuring LLVM/Clang.
