C's wonderful declarator syntax makes this rather non-trivial. I've chosen
to implement this by pushing cleanups that will get called at the end of
a "full type", in reverse order.
With much thanks to cdecl.org (created by Peter Ammon from the AppKit team).

The @objc validator still rejects UnsafePointers of any non-mapped type,
so things like "NSRect *" and "MyClass **" get rejected, but this code
will do the right thing for those as well.

These get translated as "id <MyProto>" and "id <MyProto, OtherProto>",
of course. There's special handling for protocol metatypes so that we get
"Class <MyProto>". (Objective-C doesn't have any other way to specify what
operations are available on a particular Class, so this is pretty important!)

This just assumes the class has already been declared. The next step here
is to add something that walks all of the referenced types /before/ starting
to print the @interface, and makes sure they've been defined or at least
forward-declared.

* Added a mode in swift-ide-test to test code completion. Unlike c-index-test,
the code completion token in tests is a real token -- we don't need to
count lines and columns anymore.
* Added support in lexer to produce a code completion token.
* Added a parser interface to code completion. It is passed down from the
libFrontend to the parser, but its functions are not called yet.
* Added a sketch of the interface of code completion consumer and code
completion results.
Note: all this is not doing anything useful yet.
