[PATCH] D53909: ADT/STLExtras: Introduce llvm::empty(); NFC

[Matthias Braun via Phabricator via llvm-commits]

MatzeB updated this revision to Diff 171837.
MatzeB added a comment.

- Add a simple unittest
- Go with the adl_begin() == adl_end() implementation for now. We can always switch to more fine grained overloading when we actually deem it necessary for performance. And after all we will probably just replace it with `std::empty()` anyway once we use C++17 in llvm.
