When updating an existing archive, llvm-ar opens the old archive into a `MemoryBuffer`, does its thing, and writes the results to a temporary file. That file is then renamed to the original archive filename, thus replacing it with the updated contents. However, on Windows at least, what would happen is that the `MemoryBuffer` for the old archive would actually be an mmap'ed view of the file, so when it came time to do the rename via Win32's `ReplaceFile`, it would succeed but would be unable to fully replace the file since there would still be a handle open on it; instead, the old version got renamed to a random temporary name and left behind.
