Replace one FIXME with another. We handle protocols just fine now. The ObjC decl will only be 0 when we have an error on the ObjC decl. I would prefer we pass in a decl that is marked as invalid. I don't think this is critical to fix now, however I'd like us to be consistent. There are currently many places that don't mark the decl as invalid (which need to be fixed)...

Refinements to Sema::GetObjcIdType()...
...
- Cache the typedef, not the type (avoids importing AST/Type.h).
- Emit an error if "id" cannot be found.
- Comment the routine and add a FIXME to reconsider how we emulate GCC's new fangled behavior. This isn't a priority for now, since almost no code depends on having "id" built-in.
- Add a test.

This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added).

Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped).
