auto merge of #12584 : alexcrichton/rust/windows-files, r=brson

These commits fix handling of binary files on windows by using the raw `CreateFile` apis directly, also splitting out the windows/unix implementations to their own files because everything was configured between the two platforms.

With this fix in place, this also switches `rustc` to using libnative instead of libgreen. I have confirmed that this PR passes through try on all bots.
