Option parsing: recognize the special -- token
Everything that comes after -- should be treated as a filename. This
enables passing in filenames that would otherwise be conflated with
command-line options.
This is especially important for clang-cl which supports options
starting with /, which are easily conflatable with Unix-style
path names.
