  Changed paths:
    M clang/include/clang/Driver/Options.td
    M clang/lib/Driver/ToolChains/MSVC.cpp
    M clang/test/Driver/cl-options.c

  Log Message:
  -----------
  Add clang-cl "vctoolsdir" option to specify the location of the msvc toolchain

Add an option to directly specify where the msvc toolchain lives for
clang-cl and avoid unwanted file and registry probes.
