Fixup debug information for the location information for __block

variables. For this to work, the backend needs to handle more complex
forms for locations.
A typical utterance would be:
%forwarding = getelementptr %0* %use_by_ref, i32 0, i32 1 ; <i8**> [#uses=1]
%0 = load i8** %forwarding ; <i8*> [#uses=1]
%1 = bitcast i8* %0 to %0* ; <%0*> [#uses=1]
%x = getelementptr %0* %1, i32 0, i32 4 ; <i32*> [#uses=1]
%2 = bitcast i32* %x to { }* ; <{ }*> [#uses=1]
call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))
Presently when selection finds something it doesn't understand, it
just avoids generating any information, which is safe, just
incomplete. Radar 6867696
