From 288bc5cdd0b31b923aa6acc314736f5303e67978 Mon Sep 17 00:00:00 2001

Subject: [PATCH] build/cmake: Switch to using llvm-build computed
 dependencies.  - I verified locally that the current dependency lists are
 identical.  - This makes add_llvm_library_dependencies() a no-op. I'll remove
 it once this    change passes the bots.
