Fix PR17239 by changing the semantics of the RemainingArgsClass Option kind

This patch aims at fixing PR17239.

This bug 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.
The LLVM side of the 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.

This is the Clang side of the patch in http://reviews.llvm.org/D4899
