[cfe-dev] Parsing VC++ headers with tool/libtooling

When I changed to second parameter to "clang-cl.exe" I get an output
argument list of {"clang-cl", "--driver-mode=cl", "main.cpp"}.

When I add that additional driver to the invocation of my tool I still get
the same set of errors.

Tool usage:
MyTool.exe main.cpp -- --driver-mode=cl
