[PATCH] D46621: [Support] call FlushFileBuffers when closing raw_fd_ostream on Windows

I won’t block or approve, but I would be extraordinarily surprised if it
turns out to be the culprit since the Windows team already confirmed it to
only be a problem with mapped file i/o (and if it weren’t, it would
probably be so common that the whole world would have blown up by now).

So probably a good idea to think about next steps (eg obtaining one of the
“corrupt” files from a buildbot)
