First, fix canonical type handling of these, since protocol qualified id's are always
canonical.  Next, enhance SemaType to actually make these when used (instead of int)
allowing them to actually be used when appropriate.  Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's.  This fixes

When constructing an ObjCIvarDecl object in Sema, provide its visibility up front instead of setting it afterwards.
This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

the standard "set these as the list of protocols" interface instead of a 
strange "set this as the size and then set each one to the value" interface.
The problem with the later is that it a) is completely different from 
everything else, b) is awkward, and c) doesn't handle the case when a
referenced protocol is invalid: it set it to null.

This meant that all clients downstream would have to handle null protocols
in the protocol list, and empirically they didn't.  Fix this by not setting
invalid protocols in the referenced protocol list, fixing the crash on 
test/Sema/objc-interface-1.m

While I'm at it, clean up some locations so that we produce:

t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
~~~~~~~~~~~~~~~~~~~~~   ^

instead of:

t.m:1:1: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^

- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.
