deterministic when faced with an ambiguity. This eliminates the
annoying test/SemaCXX/using-directive.cpp failure.

failures that involve malformed types, e.g., "typename X::foo" where
"foo" isn't a type, or "std::vector<void>" that doens't instantiate
properly.
Similarly, be a bit smarter in our handling of ambiguities that occur
in Sema::getTypeName, to eliminate duplicate error messages about
ambiguous name lookup.
This eliminates two XFAILs in test/SemaCXX, one of which was crying
out to us, trying to tell us that we were producing repeated error
messages.

Also, put Objective-C protocols into their own identifier
namespace. Otherwise, we find protocols when we don't want to in C++
(but not in C).

scopes where the name would be considered a redeclaration if we know
that we're declaring or defining that tag.
