[PATCH] D36971: [CMAKE] Move version control macros to ADDLLVM so they can be reused by clang, etc.

> I just checked that this patch is working correctly from clang. I am just wondering if there is a possibility of using clang only without llvm. If this is the case, clang might need its own version control macros ? Or no such case.

LLVM is required to build clang, either in-tree or found via llvm-config for out-of-tree builds.

For in-tree builds, AddLLVM.cmake gets included by llvm/CMakeLists.txt, whereas it will be included by clang/CMakeLists.txt for out of tree builds.
