- This disables the system include directories, but not the compiler builtin
directories. Useful for projects that want to use things like the intrinsic
headers, but are otherwise freestanding.
- I'm willing to reconsider the option naming, I also considered providing an
explicit -builtinc (which would match -nobuiltininc), but this is more
consistent with existing options.

to operate "as if" in a certain working directory.
- For now, we just implement this by changing the actual working directory, but
eventually we would want to handle this transparently. This is useful to
avoid an extra exec() pair in some situations, and will be something we would
want to support for more flexibility in using the Clang libraries.

This adds an option to set the _MSC_VER macro without
recompiling. This is very useful when testing compatibility
with the Windows SDK and c++stdlib headers.

library to use.
- This is currently useful for testing libc++; you can now use 'clang++
-stdlib=libc++ t.cpp' to compile using it if installed.
- In the future could also be used to select other standard library choices if
alternatives become available (for example, to use an alternate C library).

- -emit-llvm isn't a stage selection option.
- Document -O4 and -flto.
- -ObjC++ and -ObjC apply to all inputs, not subsequent ones.
- Some versions of pod2man aren't happy about the comment after =over=?
- Some minor grammar fixes.

- Mirroring LLVM's docs/CommandGuide, a place to put .pod files which
are used to generate man/html/etc documentation for tools provided
as part of clang.
