Make atomic ccache replacement work on Windows
Commit 371f09d4bf4ca0c7ba15c5ef909bc35307ed9cc3 relies on POSIX
rename() semantics for atomic ccache replacement. Windows rename()
fails if the destination file exists. Add a fallback to ReplaceFile()
when this happens. We may be able to do better using
FILE_RENAME_FLAG_POSIX_SEMANTICS (added in Windows 10 update 1067) but
this should generally suffice.
