[PATCH] D131313: [Support] Use constexpr if

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

I don't think we should use `if constexpr` if we don't actually require it's semantics. A normal `if` will get optimized just fine. The only actual change here is that the llvm_is_multithreaded() definition gets moved into the header, which allows this to optimize without LTO.
