mmap(win32): avoid copy-on-write when it is unnecessary
Often we are mmap()ing read-only. In those cases, it is wasteful to map in
copy-on-write mode. Even worse: it can cause errors where we run out of
space in the page file.
So let's be extra careful to map files in read-only mode whenever
possible.
