fix several problems with the protocol qualified id handling where id was implicit.

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

changes the testcase to be substantially reduced.

Refine ObjCPropertyImplDecl:

- Remove a bunch of setXXX methods until we actually need them. This cleans up the
interface, and makes the object immutable until we have a reason to be mutable.

- Remove enum value OBJC_PR_IMPL_None since it was never used.

- Remove instance variable 'PropertyImplKind PropertyImplementation;'. This is
  not needed because we can tell if ObjCPropertyImplDecl represents @synthesize
  if 'ObjCPropertyDecl *PropertyDecl' is not null.

Fix RewriteObjC::RewriteObjCThrowStmt() to respect whitespace between the @ and throw.

Rework codegen of case ranges
 - Fix multiple issues with the way case ranges were emitted, see test
   cases details about the specific issues.

 - The root issue was not being careful about how basic blocks were
   emitted which led to them being chained together incorrectly,
   resulting in improper control flow.

 - Fixes <rdar://problem/6098585>

Fix Sema::ActOnClassMessage() to pass through the identifier for "super".
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).
