This patch contains the LLVM side of the fix of PR17239. This bug that happens because the /link (clang-cl.exe argument) is marked as "consume all remaining arguments". However, when inside a response file, /link should only consume all remaining arguments inside the response file where it is located, not the entire command line after expansion. My patch will change the semantics of the RemainingArgsClass kind to always consume only until the end of the response file when the option originally came from a response file. There are only two options in this class: dash dash (--) and /link.
