[PATCH] Fix PR17239 by changing the semantics of the RemainingArgsClass Option kind

[Reid Kleckner]

So, /link actually only consumes arguments until end-of-line. See http://llvm.org/PR17239. If we're going to add support for /link in response files, we should actually get it right. We haven't fixed this yet because most MSVC build systems don't use the compiler to run the link step.
