[PATCH] D52998: [benchmark] Disable exceptions in Microsoft STL

Yes. I understand. At the moment, exception handling flags are generated based on `BENCHMARK_ENABLE_EXCEPTIONS`  in `utils/benchmark/CMakeLists.txt` .  However, `_HAS_EXCEPTIONS` is not defined based on this (code below). The warnings are a result of this mismatch.

  if (NOT BENCHMARK_ENABLE_EXCEPTIONS)
      add_cxx_compiler_flag(-EHs-)
      add_cxx_compiler_flag(-EHa-)
    endif()

I think it makes most sense to add definition for `_HAS_EXCEPTIONS=0 `here as opposed to modifying `llvm/CMakeLists.txt`.  Please correct me if I'm wrong. I'm not too familiar with CMake. @kbobyrev Please let me know what you think as well since you had suggested `llvm/CMakeLists.txt`.
