[PATCH] D23654: [CMake] Rename back SIMPLE_SOURCE to compile as C++

[Chris Bieneman via llvm-commits]

@compnerd, if it matters, the llvm/runtimes directory can now ensure that the builtin libraries are built before the sanitizers are configured.

A solution for libunwind also isn't too difficult via the runtimes directory because we can configure libunwind with compiler-rt and connect the dependencies.
