This patch is the first step to make module-map-files modular (instead
of requiring a single "module.map"-file per include directory). This
step adds a new "extern module" declaration that enables
module-map-files to reference one another along with a very basic
implementation.
The next steps are:
* Combine this with the use-declaration (from
http://llvm-reviews.chandlerc.com/D1546) in order to only load module
map files required for a specific compilation.
* Add an additional flag to start with a specific module-map-file (instead
of requiring there to be at least one "module.map").

It was really hard to tell that modules are experimental. This makes it
really clear by
* Noting the experimental status in the title.
* Moving the "warning" above the table of contents.

- There is no reason to have a modules specific flag for disabling
autolinking. Instead, convert the existing flag into -fno-autolink (which
should cover other autolinking code generation paths like #pragmas if and
when we support them).

This option can be useful for end users who want to know why they
ended up with a ton of different variants of the "std" module in their
module cache. This problem should go away over time, as we reduce the
need for module variants, but it will never go away entirely.
