`/notify_update` is an undocumented feature used by CMake. From their usage, it looks like this feature just changes `mt`'s exit code if the output file was changed. See https://gitlab.kitware.com/cmake/cmake/-/blob/master/Source/cmcmd.cxx#L2300 this is also consistent with some testing I have done of the mt.exeshipped with Visual Studio. See also the comment at https://gitlab.kitware.com/cmake/cmake/-/blob/master/Source/cmcmd.cxx#L2440. There might be a more performant way to implement this by first checking calling `llvm::sys::fs::file_size()` and if it is the same as the new output's size use `llvm::WritableMemoryBuffer` and fallback to `llvm::FileOutputBuffer` otherwise, but these don't inherit from a common ancestor so any implementation doing this would be really ugly.
