[PATCH] D26255: [cmake] Add LLVM_ENABLE_DIA_SDK option, and expose it in LLVMConfig

Whether or not to use `WIN32` or `MSC_VER` is always a tricky question.  I would probably use `MSC_VER` in this case.  Because `WIN32` can be defined if you're using GCC / MinGW for example, and DIA won't won't work under those scenarios.
