I realized after cleaning out old test outputs that this causes an issue with 
the handling of save-temps for ThinLTO distributed backends. Previously they 
were adding the task ID of "0", and this became unsigned -1 after this change. 
I sent an LLVM patch D46488 to change that so no Task ID is added to the path 
if it is -1, and updated the test in this clang patch.
