- Follows emission scheme used by llvm-gcc, i.e. invent an id for
   each label whose address is taken and replace each indirect goto by
   a switch to each possible target.
 - Currently we emit a switch for each indirect goto instead of
   merging them as llvm-gcc does.

Finally fix PR2189.  This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

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

This fixes a critical rewriter bug (<rdar://problem/6096760> clang ObjC rewriter: 'self' not expected value in class method called with 'super').

Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr).

llvm-svn: 53994

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).

Fix protocol lists to pass down proper location info, so we get diagnostics
like this:

@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^
