Really basic setup to use clang in msvc mode.

We actually don't really want to do a lot, even though clang is msvc compatible
|

in this mode, that doesn't mean we're actually using msvc.
|

It's probably the best to leave it to the user, we can assume msvc mode if the user

uses the clang-cl frontend, but this module only concerns itself with the gcc-like frontend.
