[PATCH] D132799: Make sure libLLVM users link with libatomic if needed

[Aaron Puchert via Phabricator via llvm-commits]

Go back to only adding libatomic. The `LLVM_SYSTEM_LIBS` contain many libraries that seem to be private dependencies only, and for now we don't properly track private vs public dependencies on component libraries.
