This was previously not-const only because it has to lazily construct a chain
of ivars the first time it is called (and after the chain is invalidated).
In practice, all the clients were just const_casting their const Decls;
all those now-unnecessary const_casts have been removed.

some common llvm types: stringref and smallvector.  This cleans up the codebase
quite a bit.

This is something of a hack, the problem is as follows:

1. we instantiate both copied of RetainPtr with the two different argument types
   (an id and protocol-qualified id).
2. We refer to the ctor of one of the instantiations when introducing global "x",
   this causes us to emit an llvm::Function for a prototype whose "this" has type
   "RetainPtr<id<bork> >*".
3. We refer to the ctor of the other instantiation when introducing global "y",
   however, because it *mangles to the same name as the other ctor* we just use
   a bitcasted version of the llvm::Function we previously emitted.
4. We emit deferred declarations, causing us to emit the body of the ctor, however
   the body we emit is for RetainPtr<id>, which expects its 'this' to have an IR
   type of "RetainPtr<id>*".

Because of the mangling collision, we don't have this case, and explode.

This is really some sort of weird AST invariant violation or something, but hey
a bitcast makes the pain go away.

It doesn't matter in practice, but it is good to be tidy.

and ConvertTypeForMem are the same for pointers, it is best to just
use ConvertType.  Thanks Eli!

types.  Fore xample, we used to lower:

struct bar { int a; };
struct foo {
 void (*FP)(struct bar);
} G;

to:

%struct.foo = type { {}* }

since the function pointer would cause recursive translation of bar and
we didn't know if that would get us into trouble.  We are now smart enough
to know that it is fine, so we get this type instead:

%struct.foo = type { void (i32)* }

Codegen still needs to be prepared for uncooperative types at any place,
which is why I let the maximally uncooperative code sit around for awhile to
help shake out the bugs.
