Commit [6d9cd9199a6fdeab0412117bcefc28f625510b61](https://reviews.llvm.org/rG6d9cd9199a6fdeab0412117bcefc28f625510b61) added a dependency on llvm to debugserver. This breaks the build. Since we don't want to add a dependency on llvm, this patch reverts the offending commit. Differential Revision: https://reviews.llvm.org/D131901
