The motivation was to save the disk usage from the memory dumps. So having the diff dump along with entire dump defeats the purpose. The verification compares the `.original.output` to the `.replay.output` anyway. Since both are now replaced by diffs, the verification from the `llvm-omp-kernel-replay` tool just compares the diffs now.
