instead of mapping the decl to a bitcast of the global to the correct
type.
 
 - GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now.

 - This solves a problem where a dangling pointer could be introduced
   by the RAUW done when replacing a forward or tentative
   definition. See testcase for more details.

 - Fixes <rdar://problem/6108358>

 - Killed useless CodeGenModule::EmitGlobalVarDeclarator, instead just
   recurse on any ScopedDecl.

remove the objc- prefix from the tests that use it.

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

like "id<foo>".  This 1) fixes an infinite loop in the parser on things
like "short<foo>" 2) emits a warning about this bogus construct and 3)
changes the testcase to be substantially reduced.

(a) removes a bogus warning.
(b) removes an undesirable usage of the ObjCMessageExpr constructor that takes an IdentifierInfo * (which I will abolish).

 - 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>
