In incompatible pointer-typed ?: expressions, add implicit conversion of RHSs to id type instead of void* if either has Objective-C object type. - This ensures the result can still be used in normal places an object can be used, like a message send. Add implicit conversions for ?: applied to qualified id types to ensure that the RHSs are compatible. - This prevents a codegen crash (creating invalid PHI nodes). - Again, this relates to the fact that qualified id types have no canonical types. - Note that the implicit type casted to is incorrect, however this doesn't currently cause problems because of the flexibility of the id type. Test cases for above. llvm-svn: 55346 2008-08-26 08:41:39 +08:00			`@protocol P0`
