> Let me know what you think about it -- I considered keeping the llvm::writeFileAtomically and migrating its underlying implementation to llvm::writeToOutput, but it doesn't seem to worth, there are only 4 in-tree usages of this API, I think it is probably better just remove it.

I think it is OK to leave only one API (f.e. llvm::writeToOutput) and remove another. It would probably be better to split this patch to  lldb, thinlto, clang and removal parts.

-                         }
-                       })) {

----------------
the call to llvm::writeToOutput is probably missed here.
