2017 changes the way you find an installed copy of
Visual Studio as well as its internal directory layout.
As a result, clang-cl was unable to find VS2017 even
when you had run vcvarsall to set up a toolchain
environment. This patch updates everything for 2017
and cleans up the way we handle a tiered search a la
environment -> installation -> PATH for which copy
of Visual Studio to bind to.
Patch originally by Hamza Sood, with some fixups for landing.

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
